e of 26 minutes a day on the app (I made this up, and we are assuming TikTok is still around in 5 years). They also report a standard deviation of 12 minutes. Assume the population is also normally distributed.
1. a) What is the likelihood of selecting a single user at random that spends at least 30 minutes a day on the app?
identified a rise in contacting STIs (sexually transmitted infections) among young adults and are interested in understanding why. The researchers measured several variables related to condom use including: likelihood of using condoms in the future, previous use of condoms, perceived ability for self-control in sexual relationships, and perceived risk for contracting STIs.
This study is looking to understand why there has been a rise in sexually transmitted infections. Participants were asked to answer 4 different questions and the results were analyzed.
Participants: Participants include 100 men and women ages ranging from 18-38. The mean age in this experiment is 24 years old and there is an equal amount of men and women.
Name of Independent Variable(s): Provide a description of all independent (or grouping) variables, including their levels. Each variable should be described separately and the name of each new variable should be indented and underlined.
Name of Dependent Variable: Provide a description of the dependent variable, including how it was operationalized.
Following the description of all your variables you should clearly state (in a sentence) the research question you intend to investigate. Next, you should say something along the lines of, “This research has the following hypotheses:
Ha: State the alternate hypothesis in BOTH conceptual and statistical form.
H0: State the null hypothesis in BOTH conceptual and statistical form
Also I need to know what analysis to complete in spss
amily has a history of phenylketonuria (PKU) including her brother after seeing her Brother struggle with PKU Amelia understands that life with PKU would be challenging and it is a challenge she is hoping to avoid for her child, Amelia, and her husband, Decided to meet with a Family planner to help them understand the chances of having a child with PKU and potentially if anything can be done to help reduce the chances of them passing this trait to their offspring
1. What is the likelihood that Amelia is a carrier for PKU?
2. Given what you know about the pedigree Of this family what are the probabilities Of Amelia having children with PKU?
3.what are the chances Amelia having children that are carriers?
