A) what are the null and alternative hypotheses? 

B) determine the test statistic __( round to two decimal places as needed )

C) determine the p-value ( round to three decimal places as needed ) 

State the final conclusion that addresses the original claim. 
A) Reject / fail to reject H0. There is ( sufficient, not sufficient) evidence to conclude that the mean of the population of ratings is (less than , equal to , not , greater than ) 7.00

### Hypothesis Testing for Speed Dating Ratings

**Data Context:**
A data set about speed dating includes "like" ratings of male dates made by female dates. The summary statistics are:
- Sample size (\(n\)) = 199
- Mean (\(\bar{x}\)) = 6.56
- Standard deviation (\(s\)) = 1.86

Given this data, we aim to test the claim that the population mean of such ratings is less than 7.00 at a 0.05 significance level. Assume a simple random sample has been selected.

---

**Steps to Conduct Hypothesis Testing:**

1. **Identify the Null and Alternative Hypotheses:**
   
   What are the null and alternative hypotheses?

   A. \( H_0: \mu = 7.00 \) 
      \( H_1: \mu < 7.00 \) 

   B. \( H_0: \mu = 7.00 \) 
      \( H_1: \mu > 7.00 \)

   C. \( H_0: \mu = 7.00 \) 
      \( H_1: \mu \ne 7.00 \)

   D. \( H_0: \mu < 7.00 \) 
      \( H_1: \mu > 7.00 \)

2. **Determine the Test Statistic:**
   
   - Provide a blank space for the student to enter the calculated test statistic. 
   - Instruction: *(Round to two decimal places as needed.)*

3. **Determine the P-Value:**
   
   - Provide a blank space for the student to enter the calculated P-value.
   - Instruction: *(Round to three decimal places as needed.)*

4. **State the Final Conclusion:**
   
   - Provide a structured sentence with blank spaces for the students to fill based on their test results.
   - Sentence Structure: \( H_0 \). There is (select evidence/no evidence) to conclude that the mean of the population of ratings is (select from drop down: <, >, or =) 7.00.
