a) What is the sampling distribution of people 25 and older who have attained an Associate's or higher degree in 2021? (i.e.What is the sampling distribution of the sample proportion, p?) Include: your calculations for np and n(1 - p), the mean of p-hat, and the calculations for the standard deviation of p-hat. Round the standard deviation of p-hat to 3 decimal places. b) Find the probability that the proportion of adults in the sample who have an Associate's or higher degree is between 0.42 and 0.46. c) Find the probability that less than 43% of adults in the sample have an Associate's or higher degree. d) Find the probability that more than 27% of the adults in the sample have an Associate's or higher degree. e) Would it be unusual if more than 45% of the adults in the sample have an Associate's or higher degree? Explain.
