In a random sample of

ten

people, the mean driving distance to work was

19.5

miles and the standard deviation was

7.3

miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a

90%

confidence interval for the population mean

μ.

Interpret the results.
