A statistical test is performed and it results in a p-value = 0.007. Using a significance level of α = 0.001, what is your final decision and conclusion?

A

Reject the null hypothesis. We do not have evidence in favor of the alternative.

B

Reject the null hypothesis. We have evidence in favor of the alternative.

C

Fail to reject the null hypothesis. We do not have evidence in favor of the alternative.

D

Fail to reject the null hypothesis. We have evidence in favor of the alternative

A traffic study was conducted on a particularly busy section of street. The peak traffic flow was averaged over a 5 day period and the following results were determined: peak flow mean = 160.4 cars; peak flow variance = 30.5 cars2 The traffic study was done to determine if more than 150 cars were passing through the section during peak periods on average. Hypothesis testing was performed, with the alternative hypothesis being that more than 150 cars are passing through...
