Need help finding test stat and p value

Bjork Larsen was trying to decide whether to use a new racing wax for cross-country skis. He decided that the wax would be worth the price if he could average less than 55 seconds on a course he knew well, so he planned to study the wax by racing on the course 8 times. His 8 race times were 54.2, 65.5, 49.5, 54.5, 49.3, 45.2, 50.5, and 44.1 5 seconds. Should he buy the wax? Explain by performing an appropriate hypothesis test. Assume the assumptions and conditions for appropriate hypothesis testing are met for the sample. Use 0.05 as the P-value cutoff level. . Choose the correct null and alternative hypotheses below. O A. Ho: H > 55 HA: H = 55 B. Ho: H =55 HA: H 55 OD. HO: H
