Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ $ 89.52. You want to test this claim. 1. The null and alternative hypothesis in symbols would be:

a. H0:μ=57.8H0:μ=57.8
H1:μ≠57.8H1:μ≠57.8

b. H0:μ≥57.8H0:μ≥57.8
H1:μ<57.8H1:μ<57.8

c. H0:μ≤57.8H0:μ≤57.8
H1:μ>57.8H1:μ>57.8

d. H0:p=57.8H0:p=57.8
H1:p≠57.8H1:p≠57.8

e. H0:p≥57.8H0:p≥57.8
H1:p<57.8H1:p<57.8

f. H0:p≤57.8H0:p≤57.8
H1:p>57.8H1:p>57.8

2. The null hypothesis in words would be:
a. The average price of textbooks in a sample is $96.28
b. The proportion of all textbooks from the store that are less than 96.28 is equal to 50%
c. The average of price of all textbooks from the store is less than $96.28.
d. The average of price of all textbooks from the store is greater than $96.28.
e. The average price of all textbooks from the store is $96.28

3. Based on a sample of 170 textbooks at the store, you find an average of 59.8 and a standard deviation of 19.8.

The point estimate is:
