### Hypothesis Testing Exercise

**Scenario:**
Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at the BC bookstore costs $78.08. You want to test this claim.

---

**Question 1:**
**The null and alternative hypothesis in symbols would be:**

- $ H_0: p \leq 78.08 $
$ H_1: p > 78.08 $

- $ H_0: \mu \leq 78.08 $
$ H_1: \mu > 78.08 $

- $ H_0: \mu = 78.08 $
$ H_1: \mu > 78.08 $

- $ H_0: p = 78.08 $
$ H_1: p \neq 78.08 $

- $ H_0: \mu = 78.08 $
$ H_1: \mu \neq 78.08 $

---

**Question 2:**
**The null hypothesis in words would be:**

- The average price of all textbooks from the store is $78.08

- The average price of textbooks in a sample is $78.08

- The proportion of all textbooks from the store that are less than 78.08 is equal to 50%

- The average price of all textbooks from the store is greater than $78.08

- The average price of all textbooks from the store is less than $78.08

---

**Scenario:**
Based on a sample of 150 textbooks at the store, you find an average of 88.08 and a standard deviation of 21.2.

---

**Question 3:**
**Calculations:**

- The point estimate is: [_____] (to 3 decimals)

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

---

**Question 4:**
**Conclusion:**

Based on this, we:

- Reject the null hypothesis

- Fail to reject the null hypothesis

---
