Question
### Hypothesis Testing: Textbook Prices at BC Bookstore

#### Problem Statement
Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $89. You want to test this claim.

#### Null and Alternative Hypotheses
The null and alternative hypothesis in symbols would be:

- \( H_0: \mu = 89 \)
- \( H_1: \mu \neq 89 \)

Options for representation:
- \( H_0: p = 89 \), \( H_1: p \neq 89 \)
- \( H_0: \mu = 89 \), \( H_1: \mu > 89 \)
- \( H_0: \mu = 89 \), \( H_1: \mu \neq 89 \)
- \( H_0: p = 89 \), \( H_1: p > 89 \)
- \( H_0: \mu = 89 \), \( H_1: \mu < 89 \)
- \( H_0: \mu = 89 \), \( H_1: \mu = 0 \)
- \( H_0: p \leq 89 \), \( H_1: p > 89 \)

#### Null Hypothesis in Words
The null hypothesis in words would be:

- The average price of all textbooks from the store is $89

Selected option:
- The proportion of all textbooks from the store that are less than 89 is equal to 50%

Other options:
- The average price of all textbooks from the store is greater than $89
- The average price of all textbooks in a sample is $89
- The average price of all textbooks from the store is less than $89

#### Statistical Analysis
Based on a sample of 80 textbooks at the store, you find an average of 99.2 and a standard deviation of 10.

#### Calculation Fields
- The point estimate is: ____ (to 3 decimals)
- The 90% confidence interval (use z*) is: ____ to ____ (to 3 decimals)

#### Conclusion
Based on the results:

- [ ] Reject the null hypothesis
- [ ] Fail to reject the null hypothesis
