Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $$ 77.95. You want to test this claim.

The null and alternative hypothesis in symbols would be:

H0:p≤77.95H0:p≤77.95
H1:p>77.95H1:p>77.95
H0:p≥77.95H0:p≥77.95
H1:p<77.95H1:p<77.95
H0:μ≤77.95H0:μ≤77.95
H1:μ>77.95H1:μ>77.95
H0:μ=77.95H0:μ=77.95
H1:μ≠77.95H1:μ≠77.95
H0:p=77.95H0:p=77.95
H1:p≠77.95H1:p≠77.95
H0:μ≥77.95H0:μ≥77.95
H1:μ<77.95H1:μ<77.95

The null hypothesis in words would be:

The proportion of all textbooks from the store that are less than 77.95 is equal to 50%
The average price of textbooks in a sample is $$ 77.95
The average of price of all textbooks from the store is less than $$ 77.95.
The average price of all textbooks from the store is $$ 77.95
The average of price of all textbooks from the store is greater than $$ 77.95.

Based on a sample of 70 textbooks at the store, you find an average of 91.55 and a standard deviation of 28.2.

The point estimate is: (to 3 decimals)

The 90 % confidence interval (use z*) is: to (to 3 decimals)

Based on this we:
