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?
The 99% confidence interval is from about 81.43 to 90.58 miles.
The 95% confidence interval is from about 82.87 to 88.33 miles.
The margin of error for 95% confidence is about 2.52 miles.
The sample isn’t large enough to use a normal distribution.
The margin of error for 99% confidence is about 3.59 miles.
