The local RCMP detachment monitors the average speed on one of our busy highways in the province. The detachment wants to find whether the mean speed is more than 110 km/h. A random speed check of 62 vehicles revealed the sample mean to be 115.5 km/h and the standard deviation of the population is 20.7 km/h. Using hypothesis testing can the detachment conclude the population speed is greater than 110 km/h at the 0.05 significance level? After completing the hypothesis test, calculate the p-value and compare this to the level of significance.
