Problem #1: A sample of 20 vehicles is outfitted with snow tires. The vehicles travel 85 km/h in winter driving conditions and apply the brakes. The sample mean and standard deviation of stopping distances for these 20 vehicles are calculated to be 160 metres and 40 metres, respectively. We would like to test whether the true mean stopping distance differs from 151 metres. Assuming stopping distances are normally distributed, at the 4% level of significance, we should: (A) Fail to reject Ho since the p-value is 0.32695. (B) Reject Ho since the p-value is 0.32695. (C) Reject Ho since the p-value is 0.15715. (D) Fail to reject Ho since the p-value is 0.15715. (E) Reject Ho since the p-value is 0.31431. (F) Reject Ho since the p-value is 0.16347. (G) Fail to reject Ho since the p-value is 0.16347. (H) Fail to reject Ho since the p-value is 0.31431.
