Interpret the residual for a student with a College GPA equal to 3.00, a high school (HS) GPA equal to 2.87 and who has read 16 books in the past year. College GPA = 1.07 + 0.178(HS) GPA+1.05 books a) The student performed better than expected. b) The student performed exactly as expected. c) The student performed worse than expected. d) Cannot be determined from the given information.What percentage of the population live in their state of birth? According to the U.S. Census Bureaus American Community Survey, the figure ranges from 25% in Nevada to 78.7% in Louisiana. The average percentage across all states and the District of Columbia is 57.7%. The data in the file Homestate are consistent with the findings in the American Community Survey. The data are for a random sample of 120 Arkansas residents and for a random sample of 180 Virginia residents. a. Formulate hypotheses that can be used to determine whether the percentage of stay-at-home residents in the two states differs from the overall average of 57.7%. b. Estimate the proportion of stay-at-home residents in Arkansas. Does this proportion differ significantly from the mean proportion for all states? Use = 0.05. c. Estimate the proportion of stay-at-home residents in Virginia. Does this proportion differ significantly from the mean proportion for all states? Use = 0.05. d. Would you expect the proportion of stay-at-home residents to be higher in Virginia than in Arkansas? Support your conclusion with the results obtained in parts (b) and (c).
- Suppose that for a recent admissions class, an Ivy League college received 2,851 applications for early admission. Of this group, it admitted 1,033 students early, rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. In the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. Counting the students admitted early and the students admitted during the regular admission process, the total class size was 2,375. Let E, R, and D represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool. Use the data to estimate P(E), P(R), and P(D). Are events E and D mutually exclusive? Find . For the 2,375 students who were admitted, what is the probability that a randomly selected student was accepted during early admission? Suppose a student applies for early admission. What is the probability that the student will be admitted for early admission or be deferred and later admitted during the regular admission process?A Wall Street Journal subscriber survey asked 46 questions about subscriber characteristicsand interests.
