A mean of 22 miles-per-gallon and a standard deviation of 5 miles-per-gallon. What is the probability that a car will get less than 21 miles-per-gallon.
Samples of size 49 are taken from a population with a σ of 17. If the mean of the sample is 25, what is the confidence interval at the 90% confidence level
Determine the mean and the standard deviation of the sample.
