Question
ment Score: 29.5% Hint Check Ans In volleyball, a libero is a defensive specialist who can substitute for any back-row player but cannot attack or block the ball when it is above the net. Because of this restriction, liberos are often some of the shortest players on a team. Suppose that Jasmine wants to play volleyball in college but is worried she is too short to be seriously considered. She read online that the average libero on a college team is 66 inches tall, but she suspects that this is too low. Jasmine selects a random sample of 15 liberos on college volleyball teams. Their heights, in i that the height of all female liberos on college volleyball teams is normally distributed. nches,are listed below. Assume 66,63, 64, 68,66, 68, 67, 66, 67,65, 69, 68,68,70,67 If you wish, you may download the data in your preferred format. Crunchlt! CsV Excel JMP Mac Text Minitab PC Text R SPSs TI Cale Jasmine decides to use a right-tailed one-sample f-test to determine whether the average height of liberos on college volleyt teams is greater than 66 in. Have the requirements for a one-sample f-test been met? If they have not been met, leave the remaining questions blank.Explanation / Answer
Below are the null and alternate hypothesis
H0: mu = 66 in
H1: mu > 66 in
From the given data we have
xbar = 66.8
s = 1.85933936
Test statistics, t = (66.8 - 66)/(1.8593/sqrt(15)) = 1.6664
p-value = 0.0589
0.05 < p < 0.1
Jasmine should not reject her null hypothesis.
There is not sufficient evidence that the mean height of liberos on college volleyball teams is greater than 66 in
