An economist wishes to determine whether the amount people drive is more than in the past. In one region of the country the number of miles driven per household per year in the past was 15.5 thousand miles. A sample of 13 households produced a sample mean of 15.51 thousand miles for the last year, with sample standard deviation 2.16 thousand miles. Assuming a normal distribution of household driving distances per year, perform the relevant test at the 0.01 level of significance.

The null and alternative hypothesis would be:

The test is: left-tailed, right-tailed, two-tailed

The test statistic is:_________________(to 3 decimals)

The p-value is:

• less than
• greater than

Based on this we:

• Reject the null hypothesis
• Fail to reject the null hypothesis
