is reported that the average American eats out at a restaurant 5.9 times per week. A random sample of 40 Americans showed that the average amount of times they ate out at a restaurant per week was 5.1 times with a standard deviation of 1.7. Is there enough evidence at the 5% level that the average American eats out less than 5.9 times per week? Set up the hypothesis test with Ho and Ha: a) Ho: p = 5.9%. The proportion of amount of times Americans eat out at a restaurant per week is 5.9%. Ha: p < 5.9%. The proportion of amount of times Americans eat out at a restaurant per week is less than 5.9%.

Set up the hypothesis test with Ho and Ha:
a) Ho: p = 5.9%. The proportion of amount of times Americans eat out at a restaurant per week is 5.9%. Ha: p < 5.9%. The proportion of amount of times Americans eat out at a restaurant per week is less than 5.9%.
b) Ho: u = 5.1. The average amount of times Americans eat out at a restaurant per week is 5.1. Ha: u < 5.1. The average amount of times Americans eat out at a restaurant per week is less than 5.1.
c) Ho: u = 5.9. The average amount of times Americans eat out at a restaurant per week is 5.9. Ha: u < 5.1. The average amount of times Americans eat out at a restaurant per week is less than 5.1.
d) Ho: u = 5.9. The average amount of times Americans eat out at a restaurant per week is 5.9. Ha: u < 5.9. The average amount of times Americans eat out at a restaurant per week is less than 5.9.
