1.Can domestic dogs understand human body cues such as leaning? The experimenter leaned toward one of two objects and recorded ...

two objects and recorded whether or not the dog being tested correctly chose the object indicated. A four-year-old male beagle named Augie participated in this study. He chose the correct object 42 out of 70 times when the experimenter leaned towards the correct object. (a) (2 points) Let the parameter of interest, π, represent the probability that the long-run probability that Augie chooses correctly. Researches are interested to see if Augie understands human body cues (better than gussing). Fill in the blanks for the null and alternative hypotheses. H0 : Ha : (b) (6 points) Based on the above context, conduct a test of significance to determine the p-value to investigate if domestic dogs understand human body cues. What conclusion will you draw with significance level of 10%? (If you use an applet, please specify which applet you use, and the inputs.) (c) (5 points) Based on the above context, conduct a test of significance to determine the p-value to investigate if domestic dogs understand human body cues. What conclusion will you draw with significance level of 5%? (If you use an applet, please specify which applet you use, and the inputs.) (d) (2 points) Are your conclusions from part (b) and (c) the same? If they are different, please provide an explanation. (e) (5 points) Shown below is a dotplot from a simulation of 100 sample proportions under the assump- tion that the long-run probability that Augie chooses correct is 0.50. Based on this dotplot, would a 90% confidence interval for π contain the value 0.5? Explain your answer. (f) (4 points) Compute the standard error of the sample proportion of times that Augie chose the object correctly. 1 (g) (5 points) (h) (3 points) question? (i) (4 points) (j) (4 points) A. B. C. Construct an approximate 95% confidence interval for π using the 2SD method. What is the margin of error of the confidence interval that you found in the previous How would you interpret the confidence interval that you found in part (g)? Which of the following is a correct interpretation of the 95% confidence level? If Augie repeats this process many times, then about 95% of the intervals produced will capture the true proportion of times of choosing the correct objective. About 95% times Augie chooses the correct objective. If Augie repeats this process and constructs 20 intervals from separate independent sam- ples, we can expect about 19 of those intervals to contain the true proportion Augie chooses the correct objective. (k) (4 points) object 21 out of 35 times. Conjecture how, if at all, the center and the width of a 99% confidence interval would change with these data, compared to the original 2SD 95% confidence interval. The center of the confidence interval would . The width of the confidence interval would . (l) (4 points) Suppose that we repeated the same study with Augie, and this time he chose the correct object 17 out of 35 times, and we also change the confidence level from 95% to 99%. Conjecture how, if at all, the center and the width of a 99% confidence interval would change with these data, compared to the original 2SD 95% confidence interval. Suppose that we repeated the same study with Augie, and this time he chose the correct The center of the confidence interval would The width of the confidence interval would . .

2.A student wants to enroll in a seminar so he/she submits her name and student number to the registrar; therefore ...

r; therefore she may be validated to become an eligible student at the university. Once the registrar verifies the student, the student indicates the seminar she wants to enroll in from the list of those available. The registrar validates the student is eligible to enroll in the seminar and that the seminar fits the student’s schedule. The registrar calculates the fees for the seminar– based on the fee published in the course catalog, applicable student fees and taxes, and informs the student. The registrar verifies with the student that she still wants to enroll in the seminar, and then enrolls the student. The registrar adds the appropriate fees to the student’s bill and provides the student with a confirmation that she is enrolled. Instructions: Using a UML tool of your choice, create a Use Case model for Enroll in a seminar. Your model should include one or more opportunities for reuse. Based on the model you developed, create a UI flow diagram that extends your Use Case model showing the UIs (screens and/or reports) used to enroll in a seminar. An UML Activity diagram can be used for the UI flow diagram. Also, please fill in the provided UI flow chart to describe the UIs in your flow diagram.
