roblem #1: A sample of 23 vehicles is outfitted with snow tires. The vehicles travel 77 km/h in winter driving conditions and apply the brakes. The sample mean and standard deviation of stopping distances for these 23 vehicles are calculated to be 166 metres and 32 metres, respectively. We would like to test whether the true mean stopping distance differs from 159 metres. Assuming stopping distances are normally distributed, at the 1% level of significance, we should: (A) Fail to reject Ho since the p-value is 0.29414. (B) Fail to reject Ho since the p-value is 0.15276. (C) Reject Ho since the p-value is 0.29414. (D) Reject Ho since the p-value is 0.30553. (E) Fail to reject Ho since the p-value is 0.30553. (F) Reject Ho since the p-value is 0.15276. (G) Fail to reject Ho since the p-value is 0.14707. (H) Reject Ho since the p-value is 0.14707.

Question
Problem #1: A sample of 23 vehicles is outfitted with snow tires. The vehicles travel 77 km/h in winter driving conditions and
apply the brakes. The sample mean and standard deviation of stopping distances for these 23 vehicles are
calculated to be 166 metres and 32 metres, respectively. We would like to test whether the true mean stopping
distance differs from 159 metres. Assuming stopping distances are normally distributed, at the 1% level of
significance, we should:
Problem #1:
(A) Fail to reject Ho since the p-value is 0.29414. (B) Fail to reject Ho since the p-value is 0.15276.
(C) Reject Ho since the p-value is 0.29414. (D) Reject Ho since the p-value is 0.30553.
(E) Fail to reject Ho since the p-value is 0.30553. (F) Reject Ho since the p-value is 0.15276.
(G) Fail to reject Ho since the p-value is 0.14707. (H) Reject Ho since the p-value is 0.14707.
