Question: Step-By-Step, 2nd look. This chapter's Step-By-Steps looked at the speeds of cars traveling on Triphammer Road in Ithaca, New York. We first found a 90% confidence interval for the mean speed to be miles per hour. Later, based on a P-value of 0.136, we failed to reject the null hypothesis that the mean was no higher than the posted 30 mph speed limit. Explain how these two results are consistent. Your explanation should discuss the confidence level, the P-value, and the decision.
