A spоrts perfоrmаnce reseаrcher is evаluating the effectiveness оf two sprint training programs ( Plyometric Training and Resistance Training) designed to improve 100-meter dash times among collegiate athletes. The goal is to determine whether there is a significant difference in the average sprint times achieved by participants in the two programs. After 6 weeks of training, sprint times (in seconds) are recorded for a sample of athletes from each group. An Excel output of the independent-samples t-test results is provided. Using a 0.05 level of significance, is there a significant difference in the average 100-meter sprint times between athletes in the two training programs? complete parts a-g a) Is this a left, right, or a two-tailed test? [a] b) The null and the alternative hypothesis for this test is [b] A) H0:µA=µB vs H1:µA=µB B) H0:µA=µB vs H1:µA < µB C) H0:µA=µB vs H1:µA > µB D) H0:µA=µB vs H1:µA ≠ µB c) The test statistic is [c] A)-2.026 B) 1.687 C) -2.766 D) 2.766d) The p-value is [d] A) 0.0088 B) 0.0044 e) Using 0.05 significance level, is the null hypothesis rejected? [f]f) The conclusion for this test is: [g] A)There is a significant difference in the average 100-meter sprint times between athletes in the two training programs B)There is no significant difference in the average 100-meter sprint times between athletes in the two training programs g)Which training program resulted in faster average sprint times?
