The speed limit on Lake Buena Vista Road is 25 miles per hour. Many residents believe the mean speed of all cars exceeds the posted speed limit and that a greater police presence should be put into effect, and radar speed signs should be located at the roadside. To test this claim, the speed of 18 randomly selected cars is recorded. The data gathered from this study are as follows: 23, 26, 24, 25, 28, 26, 23, 24, 27, 25, 27, 24, 25, 23, 22, 25, 24, and 25 miles per hour with a standard deviation of 1.55. What is the calculated p-value and t-statistic?
