Use the information to construct 90% and 99% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals.

Researchers surveyed a random sample of

32

U.S. workers ages 16 years and over who did not work from home and asked how long (in minutes) it takes them to get from home to work. The responses are listed.

27	45	35	45	26	24	22	37	18	46	17	36	29	35	34	14
74	16	7	55	26	56	27	71	40	26	20	43	31	26	62	87

Construct the 90% and 99% confidence intervals for the population mean. Which interval is wider? If convenient, use technology to construct the confidence intervals.

(Round to one decimal place as needed.)
