t is well known among hockey fans that the National Hockey League (NHL) has been trying to increase goal scoring. The following table gives a set of summary statistics from the 2010 - 2011 and 2018 - 2019 NHL seasons. Assuming that the data from each season are independent simple random samples, complete the following exercises: At the 5% significance level do the data provide sufficient evidence that the average number of goals scored in the 2018 - 2019 season is greater than the average number of goals scored in the 2010 - 2011 season? Compute a 95% confidence interval for the difference between the average number of goals scored in the 2010 - 2011 season and the 2018 - 2019 season. Do the results of the hypothesis test and confidence interval agree? Explain.
