Does 10K running time decrease when the runner listens to music? Nine runners were timed as they ran a 10K with and without listening to music. The running times in minutes are shown below. Running Time 45 42 42 52 48 51 36 47 45 Without Music 47 54 43 62 51 52 42 59 51 Assume a Normal distribution. What can be concluded at the the cx = 0.10 level of significance? For this study, we should use t-test for the difference between two dependent population means Houd O a. The null and alternative hypotheses would be: H₁: ud O b. The test statistic With Music c. The p-value = 0.0007 0 0 (please enter a decimal) (Please enter a decimal) -4.786 x (please show your answer to 3 decimal places.) x (Please show your answer to 4 decimal places.)
