Answer:
Reject <em>H</em>₀ if: or .
Step-by-step explanation:
The hypothesis for the one-tail t-test is:
<em>H</em>₀: The population mean is 100, i.e. <em>μ</em> = 100.
<em>Hₐ</em>: The population mean is less than 100, i.e. <em>μ</em> < 100.
The significance level of the test is, <em>α</em> = 0.05.
The number of observations in the sample is, <em>n</em> = 25.
The degrees of freedom of the test is:
df = n - 1
= 25 - 1
= 24
Compute the critical value of <em>t</em> as follows:
*Use a <em>t</em>-table.
The rejection region can be defined as follows:
Reject <em>H</em>₀ if: or .
The range is the difference between the longest hike and the shortest hike.
Longest = 5
Shortest = 1
Range = 5-1 = 4 miles
