Question

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 68.85. You want to test this claim.

The null and alternative hypothesis in symbols would be:

H0:p≥68.85
H1:p<68.85

H0:p≤68.85
H1:p>68.85

H0:μ=68.85
H1:μ≠68.85

H0:μ≤68.85
H1:μ>68.85

H0:p=68.85
H1:p≠68.85

H0:μ≥68.85
H1:μ<68.85

The null hypothesis in words would be:

The average of price of all textbooks from the store is less than $$ 68.85.
The average of price of all textbooks from the store is greater than $$ 68.85.
The average price of textbooks in a sample is $$ 68.85
The proportion of all textbooks from the store that are less than 68.85 is equal to 50%
The average price of all textbooks from the store is $$ 68.85

Based on a sample of 90 textbooks at the store, you find an average of 67.05 and a standard deviation of 15.6.

The point estimate is: (to 3 decimals)

The 95 % confidence interval (use z*) is: ______ to _____(to 3 decimals)

Based on this we:
