Company is developing a new high-performance wax for cross country ski racing. 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 59.5, 64.7, 46.6, 54.8, 47.1, 46.1, 52.2, and 41.6 seconds to complete the test course. Complete parts a and b below. 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. H0: muless than55 vs. HA: muequals55 B. H0: muequals55 vs. HA: mugreater than55 C. H0: mugreater than55 vs. HA: muequals55 D. H0: muequals55 vs. HA: muless than55'

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
