Solution :
Given that,
s = 7.8 miles
n = 98
a.) Hypothesis:
Test Statistic:
t = 2.031
P - value = 0.0225
if P- value < 0.05 then reject H0.
P-value = 0.0225 < 0.05, we reject H0.
In general, if we end up rejecting the null hypothesis when conducting a hypothesis test, we say our results are statistically significant
