The large airline company, Cloudscape, knows from experience that only 77% of the passengers booked for flights actually show up.圖Suppose that we will take a random sample of 8 Cloudscape passengers. Let p represent the proportion of passengers from thesample who show up for their flight. Consider the sampling distribution of the sample proportion p.Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimalplaces, rounding if needed.(a) Find µa (the mean of the sampling distribution of the sample proportion).Ha = ||(b) Find on (the standard deviation of the sampling distribution of the sample proportion).on =vity5CheckSave For LaterSubmit Assignmenthat© 2022 McGraw Hill LLC.
