Question

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $$ 52.6. You want to test this claim.

The null and alternative hypothesis in symbols would be:

H0:μ≤52.6H0:μ≤52.6
H1:μ>52.6H1:μ>52.6
H0:μ=52.6H0:μ=52.6
H1:μ≠52.6H1:μ≠52.6
H0:p≥52.6H0:p≥52.6
H1:p<52.6H1:p<52.6
H0:p≤52.6H0:p≤52.6
H1:p>52.6H1:p>52.6
H0:μ≥52.6H0:μ≥52.6
H1:μ<52.6H1:μ<52.6
H0:p=52.6H0:p=52.6
H1:p≠52.6H1:p≠52.6

The null hypothesis in words would be:

The average price of textbooks in a sample is $$ 52.6
The average of price of all textbooks from the store is greater than $$ 52.6.
The average price of all textbooks from the store is $$ 52.6
The proportion of all textbooks from the store that are less than 52.6 is equal to 50%
The average of price of all textbooks from the store is less than $$ 52.6.

Based on a sample of 90 textbooks at the store, you find an average of 48.4 and a standard deviation of 15.6.

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
