Question

s to estimate the true proportion of county college ("c.c") students in her state (AD). She is able to t e students received an AD. 120pts those c.c. students, and 64 of those students received gree (AD). She is able to take a simple random sample of n -100 ptst hold for the Rowan student to be able to calculate her confidence interval? Are they true? [5 pts in her state that receive an te down the calculate dhe fomla, plug in the appropriate numbers (except zt or t),.and then er each of the following Find her 90% confidence interval for the true proportion of cc. studen AD. B to write down the calculated interval. [8 pts] c) Assume that the confidence interval in b) was calculated correctly. Consid statements, and then circle TRUE or FALSE. [7 pts) (i) The true proportion of c.c. students in her state, that receive an AD, is contained in that specific confidence interval in b) FALSE TRUE (ii) If we take many, many random samples of size n-100, and for each correctly calculate a 90% confidence interval, then about 90% of all of those intervals will contain the true proportion o с.с. students in that state that receive an AD. TRUE FALSE (iii) 90% is the probability that the true proportion of co contained in that specific confidence interval in b) students in her state, that receive an
