1.In order to determine the average price of hotel rooms in Atlanta, a sample of 53 hotels were selected. It was determined that the test statistic (z) was $1.79. We would like totestwhether or not the average room price issignificantlydifferentfrom$110.Population standard deviation is known to us.

Compute the p-value.

2.In order to determine the average price of hotel rooms in Atlanta.Using a 0.1 level of significance, we would liketo testwhether or not the average room price is significantly differentfrom $110.The population standard deviation is known to be $16. Asample of 64 hotels was selected.Thetest statistic (z) is calculatedand it is -1.67.

We conclude that the average price of hotel rooms in Atlanta is NOT significantly different from$110.(Enter 1if the conclusion is correct. Enter 0 if the conclusion is wrong.)

3.In order to determine the average price of hotel rooms in Atlanta.Using a 0.1 level of significance, we would liketo testwhether or not the average room price is significantly differentfrom $110.The population standard deviation is known to be $16. Asample of 64 hotels was selected.The p-value associatedwith the test statistic (z) is calculated and it is0.19.

We conclude that the average price of hotel rooms in Atlanta is NOT significantly different from$110.(Enter 1if the conclusion is correct. Enter 0 if the conclusion is wrong.)

4.A sample of 30 account balances of a credit company showed an average balance of $1,180 and a standard deviation of $125. You want to determine if the mean of all account balancesissignificantlygreaterthan $1,150. Assume the population ofaccount balances is normally distributed.

Compute the p-value for this test.

5.A sample of28account balances of a credit company was taken to testwhetherthe mean of all account balancesissignificantlygreaterthan$1,150.Using the samplestandard deviation,the test statistic (t) was calculated to be$1.89.We use a 0.05 level of significance. Assume the population ofaccount balances is normally distributed and the population standard deviation is unknown to us.

We conclude that the mean of all account balancesis significantly greaterthan$1,150.(Enter1ifthe conclusion iscorrect.Enter0ifthe conclusion is wrong.)
