K A 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 (selected at random) are 54.9, 63.7, 48.1, 53.9, 49.3, 47.4, 53.7, and 44.9 seconds to complete the test course. Should they market the wax? 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. Ο A. Ho:μ = 55 HAH55 Calculate the test statistic. ... t= OB. Ho:μ>55 HA:μ = 55 OD. Ho:μ<55 HAH=55 (Round to three decimal places as needed.) Calculate the P-value. P-value= (Round to four decimal places as needed.) Choose the correct clusion below. A. No, do not market the wax as there is insufficient…

The hypotheses Ho pW = pm Ha pw ≠ pm were tested and had a p-value of .08, the correspondingconfidence interval…. a. will contain .08 b. will not contain .08 c. will contain 0 d. will not contain 0 e. will have 2 positive #s

For the statement below, write the claim as a mathematical statement. State the null and alternative hypotheses and identify which represents the claim. A laptop manufacturer claims that the mean life of the battery for a certain model of laptop is less than 9 hours. Write the claim as a mathematical statement. OA. μ=9 OD. H>9 Choose the correct null and alternative hypotheses below. OA. Ho: *9 OB. Ho: Hs9 Ha: H=9 H₂:μ>9 OB. us9 OE. *9 OD. Ho: 9 is the claim OD. The alternative hypothesis Ha: #9 is the claim O E. The null hypothesis Ho: 29 is the claim. O F. The null hypothesis Ho: μ = 9 is the claim OC. μ29 OF. μ9 Ha:μs9 ⒸF. Ho: 29 H₂:μ<9

Please no written by hand solution and no img . Pairs of hypotheses about a claim (a statistic of the population, like its mean, μ) include the following:   (A) H0: μ ³ k and Ha: μ < k, where k is some value   (B) H0: μ = k and Ha: μ ≠ k, where k is some value   (C) H0: μ > k and Ha: μ £ k, where k is some value   (D) H0: μ £ k and Ha: μ > k, where k is some value   (E) H0: μ < k and Ha: μ ³ k, where k is some value
