A car manufacturer crash tests a certain model of car and measures the impact force. The test and model in question produce impact forces that are normally distributed with a mean of 303030 metric tons and a standard deviation of 1.51.51, point, 5 metric tons. Suppose that the manufacturer tests a random sample of 333 cars and calculates the sample mean impact force. Assume that the cars in the sample are independent.
What will be the shape of the sampling distribution of the sample mean impact force?
