Correlation and regression analysis from start to finish:To investigate the relationship between class attendance and performance, an education re-searcher selects for study a multiple section introductory statistics course at a large university.Instructors agree to keep an accurate record of attendance throughout one semester. At theend of the semester 26 students are selected at random. For each student in the sample, twomeasurements are made: the number of days the student was absent (r) and the student's scoreon the common final exam (y).

The COVID-19 antibodies present were measured and recorded in a sample of healthy adults injected with a placebo (Group 1) and for a sample of healthy adults injected with a COVID-19 vaccine (Group 2). A 96% confidence interval for ul-u2 was computed as follows: (-750 GMT, -550 GMT) Interpret the endpoints of this interval in the context of this problem. Do not use the word "difference" in your answer.

Assume we wish to test to see if the mean starting salary of statistics professors is different than the mean starting salary of biology professors: Let Ho: µStat = µBio versus Ha: µStat µBio at the alpha = .05 level of significance and we found the following 95% confidence interval: (126, 610) for µStat - µBio. We would reject Ho. We would Fail to Reject Ho. We would reject Ho based on a 90% confidence interval. We would fail to reject Ho based on a 90% confidence interval. Assume that we use the same sample to construct the 90% confidence interval. Please pick a choice from the following 4 options.
