We can use the
P
-value approach as well to perform the hypothesis test.
:
= 32 miles
:
32 miles
:
P
-value = 0.0425 (from
Figure 14-10
)
: For a significance level of
= 0.05, reject the null hypothesis if the
P
-value = 0.0425 <
= 0.05 (5%).
Conclusion
: Since 0.0425 < 0.05, reject
. There is sufficient sample
evidence to refute the Dean’s claim. The sample evidence does not support
the Dean’s claim that the average distance commuting students travel to the
campus is 32 miles at the 5% level of significance.
