A delivery company is logging the number of miles each employee drives each day. The company found an average of about 85.6 miles. Assume
that the standard deviation is 9.85 miles and that a random sample of 50 drivers was used to determine the average. Which statements are true
about this situation?
1. The margin of error for 99% confidence is about 3.59 miles.
2. The 95% confidence interval is from about 82.87 to 88.33 miles.
3. The margin of error for 95% confidence is about 2.52 miles.
4. The 99% confidence interval is from about 81.43 to 90.58 miles.
5. The sample isn't large enough to use a normal distribution.
