Suppose that BC financial ald alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 78.08. You want to test this claim. The null and alternative hypothesis in symbols would be: O Ho:ps 78.08 Hp> 78.08 O Ho:aS 78.08 Hp> 78.08 O Ho:p 78.08 Hip# 78.08 O Ho:p 278.08 H:p< 78.08 O Hạ: 2 78.08 H:p<78.08 O Ho:u = 78.08 H:p # 78.08 The null hypothesis in words would be: O The average price of all textbooks from the store is $ 78.08 O The average price of textbooks in a sample is $ 78.08 O The proportion of all textbooks from the store that are less than 78.08 is equal to 50%6 O The average of price of all textbooks from the store is greater than $ 78.08. O The average of price of all textbooks from the store is less than $ 78.08. Based on a sample of 150 textbooks at the store, you find an average of 88.08 and a standard deviation of 21.2. The point estimate is: (to 3 decimals) The 95 % confidence interval (use z*) is: to (to 3 decimals) Based on this we: O Reject the null hypothesis O Fail to reject the null hypothesis

Transcribed Image Text:Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC
bookstore costs $ 78.08. You want to test this claim.
The null and alternative hypothesis in symbols would be:
O Ho:p< 78.08
H:p> 78.08
O Ho: < 78.08
H:p > 78.08
O Ho:p = 78.08
H:p 78.08
O Ho:p 2 78.08
H1:p < 78.08
O Ho:42 78.08
H:p < 78.08
O Ho: u = 78.08
H:p 78.08
The null hypothesis in words would be:
O The average price of all textbooks from the store is $ 78.08
O The average price of textbooks in a sample is $ 78.08
O The proportion of all textbooks from the store that are less than 78.08 is equal to 50%
O The average of price of all textbooks from the store is greater than $ 78.08.
O The average of price of all textbooks from the store is less than $ 78.08.
Based on a sample of 150 textbooks at the store, you find an average of 88.08 and a standard
deviation of 21.2.
The point estimate is:
(to 3 decimals)
The 95 % confidence interval (use z*) is:
to
(to
3 decimals)
Based on this we:
O Reject the null hypothesis
O Fail to reject the null hypothesis
