Question
### Hypothesis Testing for Golf Ball Diameter

#### Problem Statement

Suppose a professional golfing association requires that the standard deviation of the diameter of a golf ball be less than 0.005 inch. Determine whether these golf balls conform to this requirement at the α = 0.01 level of significance. Assume that the population is normally distributed.

#### Data

The diameters of the golf balls provided for the test are as follows:
- 1.622
- 1.677
- 1.678
- 1.679
- 1.681
- 1.684
- 1.684
- 1.678
- 1.684
- 1.684
- 1.677

#### Hypothesis Formulation

- **Null Hypothesis (H₀):** 
  The standard deviation of the golf ball diameter is 0.005 inch or more.

- **Alternative Hypothesis (H₁):**
  The standard deviation of the golf ball diameter is less than 0.005 inch.

#### Instructions for Hypothesis Testing

1. **Select the Null and Alternative Hypotheses:**
   Use the drop-down menus to select the correct symbols and conditions for the null and alternative hypotheses.
   
2. **Determine the Test Statistic:**
   Calculate the standard deviation from the sample data provided and compare it to the defined threshold of 0.005 inch.

3. **Decision Rule:**
   At a significance level of α = 0.01, determine if the calculated standard deviation supports the alternative hypothesis.

4. **Conclude:**
   Based on the comparison and the level of significance, conclude whether the golf ball diameters conform to the requirement.

#### Interactive Features

- The web interface provides drop-down options for selecting hypotheses and buttons for clearing inputs or checking the correctness of selected hypotheses.
