Question

A meteorologist who sampled 10 thunderstorms found that the average speed at which they traveled across a certain state was 12 miles per hour. The standard deviation of the sample was 4.8 miles per hour. Round the final answers to two decimal places. Find the 95% confidence interval of the mean. Assume the variable is normally distributed. If a meteorologist wanted to use the highest speed to predict the times it would take storms to travel across the state in order to issue warnings, what figure would the meteorologist likely use? The meteorologist should use miles per hour for the prediction.

Explanation / Answer

The highest speed of the confidence interval is 15.43

Hence,

Meteorologist should use 15.43 miles per hour for the prediction.
