Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 79.12. You want to test this claim. The null and alternative hypothesis in symbols would be: O Ho:u 2 79.12 H1:4 < 79.12 O Ho:p < 79.12 H1:p > 79.12 O Ho:p = 79.12 H1:p # 79.12 O Ho:H < 79.12 H:4 > 79.12 O Ho:p 2 79.12 H1:p < 79.12 O Ho:u = 79.12 H1:µ 7 79.12 The null hypothesis in words would be: OThe average price of all textbooks from the store is $ 79.12 O The average price of textbooks in a sample is $ 79.12 O The average of price of all textbooks from the store is greater than $ 79.12. OThe proportion of all textbooks from the store that are less than 79.12 is equal to 50% OThe average of price of all textbooks from the store is less than $ 79.12. The population standard deviation is known to be 10 and based on a sample of 50 textbooks at the store, you find an average of 93.32. The point estimate is: The 95 % confidence interval is: to (to 3 decimals) Based on this we: O Reject the null hypothesis O Fail to reject the null hypothesis

claim. The null and alternative hypothesis in symbols would be:
O Ho:u 2 79.12
H1:4 < 79.12
O Ho:p < 79.12
H1:p > 79.12
O Ho:p = 79.12
H1:p # 79.12
O Ho:H < 79.12
H:4 > 79.12
O Ho:p 2 79.12
H1:p < 79.12
O Ho:u = 79.12
H1:µ 7 79.12
The null hypothesis in words would be:
OThe average price of all textbooks from the store is $ 79.12
O The average price of textbooks in a sample is $ 79.12
O The average of price of all textbooks from the store is greater than $ 79.12.
OThe proportion of all textbooks from the store that are less than 79.12 is equal to 50%
OThe average of price of all textbooks from the store is less than $ 79.12.
The population standard deviation is known to be 10 and based on a sample of 50 textbooks at the store, you find an average of 93.32.
The point estimate is:
The 95 % confidence interval is:
to
(to 3 decimals)
Based on this we:
O Reject the null hypothesis
O Fail to reject the null hypothesis
