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