Question

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $$ 92.38. You want to test this claim.

The null and alternative hypothesis in symbols would be:

H0:p=92.38
H1:p≠92.38
H0:μ=92.38
H1:μ≠92.38
H0:μ≥92.38
H1:μ<92.38
H0:μ≤92.38
H1:μ>92.38
H0:p≤92.38
H1:p>92.38
H0:p≥92.38
H1:p<92.38

The null hypothesis in words would be:

The average price of all textbooks from the store is $$ 92.38
The average of price of all textbooks from the store is greater than $$ 92.38.
The average price of textbooks in a sample is $$ 92.38
The proportion of all textbooks from the store that are less than 92.38 is equal to 50%
The average of price of all textbooks from the store is less than $$ 92.38.

Based on a sample of 150 textbooks at the store, you find an average of 89.58 and a standard deviation of 11.4.

The point estimate is: (to 3 decimals)

The 99 % confidence interval (use z*) is: to (to 3 decimals)

Based on this we:

Reject the null hypothesis
Fail to reject the null hypothesis
