Transcribed Image Text:### Golf Ball Diameter Hypothesis Testing
A golf association requires that golf balls have a diameter of 1.68 inches. To determine if golf balls conform to the standard, a random sample of golf balls was selected. Their diameters are shown in the accompanying data table. Do the golf balls conform to the standards? Use the α = 0.05 level of significance.
#### Data Table
The data table provides the diameters (in inches) of the sampled golf balls:
- 1.683
- 1.677
- 1.682
- 1.685
- 1.678
- 1.685
- 1.684
- 1.684
- 1.673
- 1.685
- 1.682
- 1.674
#### Steps for Hypothesis Testing
1. **Determine the Appropriate Hypotheses:**
- \( H_0 \): The golf balls conform to the standard (the mean diameter is 1.68 inches).
- \( H_1 \): The golf balls do not conform to the standard (the mean diameter is not 1.68 inches).
2. **Find the Test Statistic:**
- Calculate the test statistic using the sample data. (Round to two decimal places as needed.)
3. **Find the P-value:**
- Obtain the P-value corresponding to the test statistic. (Round to three decimal places as needed.)
#### Conclusion from the Hypothesis Test
Based on the obtained P-value and comparing it with the significance level of α = 0.05, make a decision:
- **Option A:**
Reject \( H_0 \). There is sufficient evidence to conclude that the golf balls do not conform to the association's standards at the α = 0.05 level of significance.
- **Option B:**
Do not reject \( H_0 \). There is not sufficient evidence to conclude that the golf balls do not conform to the association's standards at the α = 0.05 level of significance.
- **Option C:**
Reject \( H_0 \). There is not sufficient evidence to conclude that the golf balls do not conform to the association's standards at the α = 0.05 level of significance.
- **Option D:**
Do not reject \( H_0 \). There is sufficient evidence to conclude that the golf balls conform to the association
