8). Suppose that BC financial aid alots a textbook stipend by claiming that the average
textbook at BC bookstore costs $$ 96.54. You want to test this claimn.
Ho:u=96.54
H1:u#96.54
The null hypothesis in words would be:
The average price of all textbooks from the store is $$ 96.54
Based on a sample of 80 textbooks at the store, you find an average of 110.14 and a
standard deviation of 12.8.
The point estimate is:
2 (to 3 decimals)
The 90 % confidence interval (use z*) is: 2
to
? (to 3 decimals)
Based on this we:?
A)Fail to reject the null hypothesis
B) Reject the null hypothesis
