Question

Each person in random samples of 247 male and 263 female working adults living in a certain town in Canada was asked how long, in minutes, his or her typical daily commute was. (Use a statistical computer package to calculate the P-value. Use u-males - u-females. Round your test statistics to two decimal places, your df to the nearest whole number and your P-value to three decimal places.)

Explanation / Answer

Answer:

MINITAB used:

Answer: 1.08

Two-Sample T-Test and CI

Sample    N Mean StDev SE Mean

1       247 30.2   24.0      1.5

2       263 27.9   24.3      1.5

Difference = (1) - (2)

Estimate for difference: 2.30

95% CI for difference: (-1.90, 6.50)

T-Test of difference = 0 (vs ): T-Value = 1.08 P-Value = 0.283 DF = 506

Two-Sample T-Test and CI

Sample    N Mean StDev SE Mean

1       247 30.2   24.0      1.5

2       263 27.9   24.3      1.5

Difference = (1) - (2)

Estimate for difference: 2.30

95% CI for difference: (-1.90, 6.50)

T-Test of difference = 0 (vs ): T-Value = 1.07 P-Value = 0.283 DF = 508

Both use Pooled StDev = 24.1552
