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.

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
