Did I Get This – Using p-values
The following two hypotheses are tested:
- Ho: The average number of miles driven per year is 12,000.
- Ha: The average number of miles driven per year is less than 12,000.
In a survey, 1,600 randomly selected drivers were asked the number of miles they drive yearly. Based upon the results, the p-value = 0.068.
Comment: Throughout this activity use a 0.05 (5%) significance level (cutoff).
