1. Let x represent the length of all baseball games in the major leagues. Suppose x has a distribution that is approximately normal with a mean length of 2.9 hours and a standard deviation of 0.5 hours. To estimate the length of baseball games in the major leagues, game officials use the average length, of a random sample of 36 games. A. Determine the mean and standard deviation of the sampling distribution of the sample mean Round the standard deviation to the thousandths place (third decimal place.) B. Is the distribution of x normal? Explain. C. Draw and label a sketch of the distribution ofx.
