A sports writer wished to see if a football filled with helium travels farther when kicked, on average, than a football filled with air. To test this, the writer used18 adult male volunteers. These volunteers were randomly divided into two groups of nine subjects each. Group 1 kicked a football filled with helium to the recommendedpressure. Group 2 kicked a football filled with air to the recommended pressure. The mean yardage for group 1 was = 30 yards with a standard deviation s1 = 8 yards.The mean yardage for group 2 was = 26 yards with a standard deviation s2 = 6 yards. Assume the two groups of kicks are independent. Let µ1 and µ2 represent the meanyardage we would observe for the entire population represented by the volunteers if all members of this population kicked, respectively, a helium and an air-filledfootball. Assume that two-sample t procedures are safe to use.Suppose the researcher had wished to test the hypothesesHo: µ1 = µ2Ha: µ1 > µ2The numerical value of the two-sample t statistic isA.36B. 1.20C. 2.57D. 4.00I think the answer is A but i want to be sure
