Each month interviewers visit about 68â,000 of the 97 million households in the region and question the occupants over 60 years of age about their retirement status. Their responses enable the interviewers to estimate the percentage of people in the labor force who are retired. Complete parts a through c. a. Define the population of interest to the interviewers.

1. The 97 million households in the region.
2. Retirement status.
3. All people in the region who are over 60 years old.
4. The 68â,000 households visited in the region

b. What variable is beingâ measured?

1. All people in the region who are over 60 years old.
2. Retirement status.
3. The 97 million households in the region.
4. The 68â,000 households visited in the region.

Is it quantitative orâ qualitative?

1. Quantitative
2. Qualitative

c. Is the problem of interest to the interviewers descriptive orâ inferential?

1. Inferential
2. Descriptive

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?

Given sin∅ = 1/3 and 0 < ∅ < π/2 ; find tan2∅ a. (4√2)/9 b. 9/7 c. (4√2)/7 d.7/9

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
