What is the answer to the question

3) According to the National Highway Traffic Safety Administration, 85% of all U.S. drivers use their seat belts. Assume this percentage represents the true population proportion of all U.S. drivers. If a random sample of 900 U.S. drivers is selected, then: a) State the mean and standard error of the SAMPLING DISTRIBUTION using the proper notation. Mean: ( to 2 decimal places) STD Error: ( to 4 decimal places) b) Can the sampling distribution be approximated by a normal distribution? If not, then state what distribution can be used. You must show work to support your answer to receive credit. ) Using the sampling distribution and the results of part a, calculate the probability (to 4 decimal places) of selecting a random sample containing at least 88% U.S. drivers who wear seat belts. Show the following: i) Draw a graph representing the sampling distribution below & shade area representing the probability. ii) MUST Show all work! Include the calculator function(s) with input values you used to solve this
