1) In a random sample of 200 Americans, 58% said they plan to spend less on their summer vacation this year than last year. a) Construct a 95% confidence interval for the proportion of all Americans who plan to spend less on their summer vacation this year than last year. b) Does your interval support that the majority of Americans would say they plan to spend less this year on their summer vacation than last year? Clearly explain your answer and reference your interval.
