The distance traveled varies directly with the time spent in motion. If d is distance and t is time taken. Then,
or
k is the constant of variation
If d = 150 miles and t = 4 hours
Considering the situation described, the hypothesis tested are given as follows:
- The null hypothesis is
- The alternative hypothesis is
At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:
At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:
