Mаrket reseаrchers studying the demоgrаphics оf sоda drinkers claim that the average age of Mountain Dew drinkers is at least that of the average age of Coke drinkers.To test their claim, the researchers randomly select 300 Mountain Dew drinkers and 300 Coke drinkers. The average age of the Mountain Dew drinkers is 30.1 with a standard deviation of 8.38 years, and the average age of Coke drinkers is 30.9 with a standard deviation of 10.47 years.Based on this data, and using an alpha=0.20, answer the following questions and test the claim.The left critical value = [left] (round to 2 decimals - if there is no left value, enter "na")The right critical value = [right] (round to 2 decimals - if there is no right value, enter "na")The test statistic = [ts] (round to 2 decimals)The result of the hypothesis test is [result] (enter "reject H0" or "fail to reject H0")Is the claim supported? [support] (enter "yes" or "no")
