A safety officer needs to prove that ? = the average speed of cars driven through a school is less than 25 mph. Assume that a random sample of 14 cars shows the average speed of 24.0 mph, with the sample standard deviation of 2.2 mph. Suppose that the speeds of cars are usually distributed. Using the T-table, for significance level of a = 0.05, are the results statistically significant?
A) No, results are not statistically significant because p-value range includes 0.05.
B) Yes, results are statistically significant because p-value range includes < 0.05.
C) No, results are not statistically significant because the p-value range does not include 0.05
D) Yes, results are statistically significant because the p-value range does not include 0.05
