to know a systematic solution to solving these types of problems that could appear on the test.
I’ve never been subjected to this type of math or algebra before and it appears as though most of these types of problems are going to be on the test.
Do you have any solutions or step-by-step methods on how to interpret and solve these problems? Thank you.

we are just barely starting to
understand.In the future, police and wrongdoing counteraction units may start to screen the degrees of
contamination in their urban communities, and convey assets to the spaces where contamination is heaviest on guaranteed
day.This may seem like the plot of a sci-fi film, however ongoing discoveries recommend that this
likely could be a beneficial practice.Why? Arising contemplates show that air contamination is connected to
disabled judgment, emotional well-being issues, more unfortunate execution in school and most worryingly
maybe, more elevated levels of crime.These discoveries are largely the really disturbing, given that more than
a big part of the total populace now live in metropolitan conditions – and a greater amount of us are going in
blocked regions than any time in recent memory. However, perhaps, he thought, there could be other unfavorable
impacts on our lives.To start with, he led an investigation seeing whether air contamination had an
impact in psychological performance.Roth and his group saw understudies taking tests on various
days – and furthermore estimated how much contamination was noticeable all around on those given days. Indeed, even a couple
days prior and a couple of days after, they discovered no impact – it's truly upon the arrival of the test
that the grade diminished altogether. To decide the drawn out impacts, Roth followed up
to perceive what affect this had eight to 10 years after the fact. In this way, he daid that regardless of whether it's a present moment
impact of air contamination, on the off chance that it happens in a basic period of life it truly can have a drawn out impact. In
2018 examination, his group broke down two years of wrongdoing information from more than 600 of London's discretionary
wards, and tracked down that more insignificant violations happened on the most dirtied days, in both rich and
poor areas.Although we ought to be careful about reaching determinations about connections, for example,
these, the creators have seen some proof that there is a causal link.Wherever the haze of
contamination ventures, wrongdoing increments. As a feature of a similar report, they thought about unmistakable regions
over the long haul, just as following degrees of contamination over the long haul. This implies that an intercession at
an early age ought to be a priority.Exposure to different poisons can cause aggravation in the
cerebrum. There are numerous potential components that may clarify how air contamination influences our
morality.Lu, for example, has shown that the simple considered contamination can impact our
brain science through its negative associations.Naturally, the scientists couldn't
truly uncover members with contamination, so they took the following best (morally supported) venture
so they asked them to truly envision living around here, and how they would feel and how their life
would be living in this climate, to make them mentally experience air contamination
versus a perfect climate. He tracked down that the member's tension expanded, and they became
more self-focussed – two reactions that could increment forceful and flippant
practices. Along these lines, by raising people groups' tension, air contamination can detrimentally affect
conduct. at the point when we are restless we are bound to punch somebody in the face, than when
we are quiet. Lead analyst Joanne Newbury, from King's College London, says she can't
however guarantee that her outcomes are causal, yet the discoveries are in accordance with different investigations proposing a
interface between air contamination and psychological wellness. "It adds to confirm connecting air contamination to
actual medical conditions and air contamination connect to dementia.

tains 40 questions on the material that we have covered during class lectures and the recorded videos (Chapters 1, 2, 3, 4, 5, 8, 9, and 10). You will be given 80 minutes to submit your answers. The final exam will be found under "Online Exams" module on Canvas.
The final exam will be available from 8:00 a.m. - 9:35 a.m. and you'll have 80 minutes to complete the test. This means that if you decide to start the exam at 9:00 a.m., you'll have 35 minutes to submit your answers. The test will no longer be available after 9:35 a.m. Please plan accordingly!
Before you take the online final exam, make sure to use "Chrome" Browser. Canvas operates best under Chrome. Also, stay as close as possible to your router in order to avoid any internet disconnection problems.
You are welcome to use your class notes and the textbook. Make sure to have a periodic table with you, a scientific calculator, and scrap paper. The final exam questions will be in the same format as the previous exams 3 & 4.
I will be available this weekend if you have questions.

adolescents. I have completed the Literature review. I have to plan a research design for the thesis. ABOUT THE THESIS:
Population- 13+ to 19 years adolescents
No of IV s- 2 that is, Gender is the First IV and Locus of Control ( LOC) is the second IV
Levels of IV- Gender has 2 levels ( male and female). LOC has two levels ( Internal Locus of Control and External Locus of Control). Both IV s are categorical variables.
List of DV s-
1. Self Esteem
2. Coping
3. Happiness
4. Academic motivation
5. Exam Anxiety
6. Life Style
Each DV will be measured by using appropriate Statistical scales. All DVs will be taken as continuous variables. All the scales measure the quantitative aspect only.
DV MEASUREMENT: Each of the scales that will be used to measure DV contains several areas or dimensions or sub-categories. For example, the self-esteem scale contains 78 items divided into 6 categories like personal, social, emotional, academic, intellectual and moral.
THESIS AIM- To check the impact of IV s on each of these DV s in isolation and also investigate the interaction effects between gender and locus of external. I will be using the SPSS package for calculations.
PROBLEM:
Problem 1: Which is the most appropriate Statistical test or design that should be used here? I believe a 2x2 ANOVA will be best suited here.
Problem 2: If I am measuring the impact of IV s on each DV in isolation, should I use several Two Way AONVA tables or a single MANCOVA table?
Problem 3: Each of the DV is measured using scales containing several dimensions. Are such dimensions of the scales need to be treated as the levels of the dependent variables? In other words, do the levels of DV are decided as per the dimensions of the scale that was used to measure the DV? If this is so, then even if I am measuring the DV s in isolation; each DV will have multiple levels, which in turn will change my design from Two Way ANOVA to perhaps MANCOVA? What is the right approach here?
Note: I have not intentionally divided DV into any levels.
Kindly help me to arrive at a statistically significant research design! If possible, kindly briefly explain the type of the design as well as the rational or suitability of the sign for my research problem.

80.Let's say that I have a data set of every time a certain person has coughed since the beginning of ...

his year. I'm looking for a formula that will tell me the probability that a person will cough x number of times in a given week.
I started with the Poisson Distribution, but Poisson doesn't seem to take into account standard deviation. To calculate the probability with Poisson, only the mean, expected value, and test value are needed, meaning the variance/standard deviation of the data could vary widely, and you'd still get the same probability distribution. For example, if someone coughed exactly 5 times everyday, you'd get the same probability distribution if this person alternated coughing 0 times one day, 10 times the next, 0 times the next day, 10 times the next, and so on.
Does my question make sense? Thanks for your help.
