Question

2. R. Stichler et al. compared two methods of measuring treadwear in a paper. Eleven tires were each measured for treadwear by two methods: one based on weight, and the other on groove wear. The data, in thousands of miles, are in the table. Use the paired ?-test to answer the following: at the 5% significance level, do the data provide sufficient evidence to conclude that, on average, the two measurement methods give different results?

a. Fill in the differences column.

b. Hypotheses: H0: ________________ Ha: __________________

c. Compute the test statistic:

d. Determine the p-value.

e. Reject null?

f. Interpret your result in a sentence.

| Weight Method | Groove Method | Difference |
|----------------|--------------|------------|
| 30.5 | 28.7 | |
| 30.9 | 25.9 | |
| 31.9 | 23.3 | |
| 30.4 | 23.1 | |
| 27.3 | 23.7 | |
| 20.4 | 20.9 | |
| 24.5 | 16.1 | |
| 20.9 | 19.9 | |
| 18.9 | 15.2 | |
| 13.7 | 11.5 | |
| 11.4 | 11.2 | |

This table compares two measurement methods: the Weight Method and the Groove Method. The third column labeled "Difference" is intended for calculating the differences between the corresponding values in the first two columns.

To complete the table, subtract each Groove Method value from its corresponding Weight Method value and fill in the Difference column. This calculation will help analyze the variations between the two methods.
