The large airline company, Tale Winds, knows from experience that only 72% of the passengers booked for flights actually show up. Suppose that we will take a random sample of 7 Tale Winds passengers. Let p represent the proportion of passengers from the sample 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 decimal places, rounding if needed. (a) Find la (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).
