Question
**Analysis of Business Owners Giving Holiday Gifts**

*Context:*  
Last year, 43% of business owners gave a holiday gift to their employees. A survey of business owners conducted this year indicates that 30% plan to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 60 business owners.

**(a) Determining the Number of Business Owners Planning to Provide Holiday Gifts This Year**

*Question*:  
How many business owners in the survey plan to provide a holiday gift to their employees this year?

*Calculation*:  
\[ \text{Number of business owners} = 0.30 \times 60 = 18 \]

---

**(b) Hypothesis Testing for Change in Proportion**

*Procedure*:  
Suppose the business owners in the sample did as they plan. Compute the p-value for a hypothesis test that can be used to determine if the proportion of business owners providing holiday gifts has decreased from last year.

1. *Find the value of the test statistic.*  
\[ \text{(Round your answer to two decimal places.)} \]

*Test Statistic Calculation*:

2. *Find the p-value.*  
\[ \text{p-value} = \ \ \ \ \ \ \ (Round your answer to four decimal places.) \]

---

**(c) Conclusion Based on the Level of Significance**

*Question*:  
Using a 0.05 level of significance, would you conclude that the proportion of business owners providing gifts decreased?

*Options*:  
- Do not reject \( H_0 \): There is sufficient evidence to conclude that the proportion of business owners providing holiday gifts has decreased from last year.
- Do not reject \( H_0 \): There is insufficient evidence to conclude that the proportion of business owners providing holiday gifts has decreased from last year.
- Reject \( H_0 \): There is sufficient evidence to conclude that the proportion of business owners providing holiday gifts has decreased from last year.
- Reject \( H_0 \): There is insufficient evidence to conclude that the proportion of business owners providing holiday gifts has decreased from last year.

*Question*:  
What is the smallest level of significance for which you could draw such a conclusion?  
\[ \text{(Round your answer to four decimal places)} \]
