SLIX wax is developing a new high performance fluorocarbon wax for cross country ski racing designed to be used under a wide variety of conditions. In order to justify the price marketing wants, the wax needs to be very fast. Specifically, the mean time to finish their standard test course should be less than 55 seconds for a former Olympic champion. To test it, the champion will ski the course 8 times. The champion's times are 55.9, 61.7, 51.4, 52.5, 46.8, 47.2, 54.9, and 42.4 seconds to complete the test course. Complete parts a) and b) below. Question content area bottom Part 1 a) Should they market the wax? Assume the assumptions and conditions for appropriate hypothesis testing are met for the sample. Assume alphaequals0.05. What are the null and alternative hypotheses? Choose the correct answer below. A. H Subscript 0: muequals55 vs. H Subscript A: mugreater than55 B. H Subscript 0: mugreater than55 vs. H Subscript A: muequals55 C. H Subscript 0: muless than55 vs. H Subscript A: muequals55 D. H Subscript 0: muequals55 vs. H Subscript A: muless than55 Part 2 What is the value of the test statistic? The test statistic is enter your response here. (Round to two decimal places as needed.) Part 3 What is the P-value of the test statistic? P-valueequals enter your response here (Round to three decimal places as needed.) Part 4 Should they market the wax
