The dataset BaseballSalaries2019 contains information about the salaries of all MLB players who were on the active roster at the start of the 2019 season. Use StatKey to answer the following questions. (1) What is the average salary for MLB players on opening day in 2019? Instructions: Go to www.lock5stat.com/StatKey, click "Mean" by "Sampling Distribu- tions," change the dataset to "Baseball Players-3e," and look at the upper right graph. (2) Select a random sample of 30 players and compute the mean salary for the players in your sample. Compare your answer to the population mean. Instructions: Change the sample size to n = 30, click "Generate 1 Sample," and look at the bottom right graph. (3) Select another random sample of 30 players and compute the mean salary. What is the average of the two sample means you've generated? Compare this to the population mean. Instructions: Click "Generate 1 Sample" again, look at the bottom right graph for the new sample mean, and then look at the big graph on the left for the average.
