$1.00 Large sample population proportion
In a survey, 1333 of 1709 adults surveyed said that they would alter their shopping habits if gas prices remain high. The article did not say how the sample was selected, but for purposes of this exercise, assume that it is reasonable to regard this sample as representative of adult Americans. Based on these survey data, is it reasonable to conclude that more than three-quarters of adult Americans plan to alter their shopping habits if gas prices remain high? (Use α = 0.01. For z round the final answer to two decimal places. For P give the answer to four decimal places.)
z = ?
P = ?
