Answer question (c) the p-value
A college entrance exam company determined that a score of 25 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean math score of 25.4 on the college entrance exam with a...

Suppose that for a recent admissions class, an Ivy League college received 2,851 appli- cations 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...

2. Suppose that a random sample of 41 state college students is asked to measure the length of their right foot in centimeters. A 90% confidence interval for the mean foot length for students at this university turns out to be (21.709, 25.091). If we now calculated a 95% confidence interval, would the new confidence interval be wider than or narrower than or the same as the original? b. Suppose two researchers want to estimate the proportion of American college...

Question 1: Each of the scenarios below represent situations in which (1) either all necessary assumptions for the unbiasedness of OLS estimators ("unbiasedness assumptions") are satisfied, or (2) one of the unbiasedness assumptions is violated. Look at the econometric model put forward in each scenario. For each scenario, state your opinion of whether or not all the unbiasedness assumptions are satisfied. If one assumption is violated, state which one does not hold true. Provide a brief explanation (no more than...
