### Investigating Tractor Skidding Distances

A recent study investigated tractor skidding distances along a road in a forest. The skidding distances (in meters) were measured at 20 randomly selected road sites. The data are provided in the table below. A logger working on the road claims that the mean skidding distance is at least 425 meters. Is there sufficient evidence to refute this claim? Use a significance level of $ \alpha = 0.10 $.

#### Hypothesis Testing
To determine if there is sufficient evidence to refute the claim that the mean skidding distance is at least 425 meters, we state the hypotheses as follows:
- $ H_0 $: $ \mu = 425 $
- $ H_a $: $ \mu < 425 $

Select the correct answer and calculate the value of the test statistic:
- **A.** $ H_0 $: $ \mu = 425 $; $ H_a $: $ \mu < 425 $ (Selected Option)
- B. $ H_0 $: $ \mu = 425 $; $ H_a $: $ \mu \neq 425 $
- C. $ H_0 $: $ \mu \geq 425 $; $ H_a $: $ \mu = 425 $
- D. $ H_0 $: $ \mu = 425 $; $ H_a $: $ \mu > 425 $
