Question

24. A sample of 30 vehicles is outfitted with snow tires. The vehicles travel 80 km/h in winter driving conditions and apply the brakes. The sample mean and standard deviation of stopping distances for these 30 vehicles are calculated to be 162 metres and 35 metres, respectively. We would like to test whether the true mean stopping distance di↵ers from 150 metres. At the 1% level of significance, we should:

    (A) reject H0, since the P-value is between 0.02 and 0.025. (B) fail to reject H0, since the P-value is between 0.025 and 0.05. (C) reject H0, since the P-value is between 0.025 and 0.05. (D) fail to reject H0, since the P-value is between 0.05 and 0.10. (E) reject H0, since the P-value is between 0.05 and 0.10.

Answer 1

option D is correct

(D) fail to reject H0, since the P-value is between 0.05 and 0.10.
