The average height of an NBA player is 6.698 feet. A random sample of 39 players heights from a major college basketball program found the mean height was 6.45 feet with a standard deviation of 5.7 inches.At a=0.01 is there sufficient evidence to conclude that the mean height less than 6.698 feet? a) State the hypotheses and identify the claim with the correct hypothesis. 51 Ho u=6.698 claim H, p*6.698 Not claim 2. Ho:U$6.698 Not claim HEU>6.698 claim 03 Hopa 6.698 Not claim H iu<6.698 claim b) Find the critical value (s). 1. CV=-2.33 2. CV=-1.65 3. CV= 1.96 c) Compute the test value: 1. Z=- 3.26 2. z=2.63 3. Z= -3.21 d) Make the decision. 1. Reject the null hypothesis. 2. Do not reject the null hypothesis. e) Summarize the results, 1. There is enough evidence to support the claim. 2.There is not enough evidence to support the claim.
