Twelve different video games showing drug use were observed. the duration times of drug use were recorded, with the times (seconds) listed below. assume that these sample data are used with a 0.05 significance level in a test of the claim that the population mean is greater than 80 sec. if we want to construct a confidence interval to be used for testing that claim, what confidence level should be used for a confidence interval? if the confidence interval is found to be 2.8 secless thanmuless than205.1 sec, what should we conclude about the claim? 81 13 565 51 0 56 191 43 187 0 2 58

High school seniors with strong academic records apply to the nation’s most selective colleges in greater numbers each year. because the number of slots remains relatively stable, some colleges reject more early applicants. suppose that for a recent admissions class, an ivy league college received 2851 applications for early admission. of this group, it admitted 1033 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 2375. 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.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?
