Now we will analyze wins on a league basis, Perform a hypothesis test to determine whether there is a difference in the mean wins per team in the American League (AL) vs mean wins per team in the National League (NL). Use a 0.05 level of signicance in your testing procedures. Additionally: You will need to know the mean number of wins per team in both the American and National Leagues. You will also need to know the standard deviations and variance of wins per team in both leagues. We are assuming that both American and National League attendance gures follow a normal distribution. We aer also assuming the two leagues are samples; the population standard deviation is NOT known. Hypothesis H0: AL Mean = NL Mean H1: AL Mean does not: NL Mean Decision Rule -t = REJECT H0 Value of Pooled Sample Variances Value of test statistic Decision: enter Reject or Do Not Reiect Based on your testing, is there a difference in the mean wins per team in the American League vs the mean wins per team in the National League? Enter Yes or No. R Provide the top 5 teams in wins for both the American and National Leagues. Enter the team name and number of wins exactly as it appears in the data set, American League National League Rank Team Vlns Team Wins 1 2 3 4 5
