Transcribed Image Text:Accordi.. previous studies, the mean distance each visitor in Greenspan National Park hikes during their visit is 24 kilometers.
The park recently closed its shuttle system, which used to transport hikers to many of the park's most popular hiking trails. Because
of this, an administrator at the park suspects the mean distance, u, is now less than 24 kilometers. The administrator chooses a
random sample of 43 visitors. The mean distance hiked for the sample is 23.1 kilometers. Assume the population standard deviation
is 4.4 kilometers.
Can the administrator conclude that the mean distance hiked by each visitor is now less than 24 kilometers? Perform a hypothesis
test, using the 0.05 level of significance.
(a) State the null hypothesis H and the alternative hypothesis H,.
Ho: 0
O<O
OSO
H7: 0
D=0
