WILL MARK BRAINLEST According to the U. S. Census Bureau’s 2014 Current Population Survey, 88% of adult U. S. residents have earned a high school diploma. Suppose we take a random sample of 120 American adults and record the proportion, p, of individuals in our sample who have a high school diploma
(A) Describe the shape, center, and spread of the sampling distribution of p?
(B) Find the probability that the sample proportion of residents who have earned a high school diploma in a random sample of 120 residents is at least 0.90.?
(C) If the sample size was only 10, would it still be possible to calculate the probability in part (b)? If so, calculate the probability. If not, explain why not?
(Each one is a question)
