The large airline company, Tale Winds, knows from experience that only 77% of the passengers booked for flights actually show up. Suppose thatwe will take a random sample of 8 Tale Winds passengers. Let p represent the proportion of passengers from the sample who show up for theirflight. 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 decimal places,rounding if needed.(a) Find un (the mean of the sampling distribution of the sample proportion).HA = ](b) Find oA (the standard deviation of the sampling distribution of the sample proportion).?ContinueSubmit AssignmentO 2022 McGraw Hill LLC.
