Question

Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $$ 62.87. You want to test this claim. The null and alternative hypothesis in symbols would be:

H0:μ=62.87
H1:μ≠62.87

The null hypothesis in words would be:

The average price of all textbooks from the store is $$ 62.87

Based on a sample of 120 textbooks at the store, you find an average of 71.47 and a standard deviation of 14.2. The point estimate is: _____________(to 3 decimals). The 90 % confidence interval (use z*) is:__________ to __________ (to 3 decimals) Based on this we:

Reject the null hypothesis
Fail to reject the null hypothesis
