Define confidence interval and degree of confidence.

Provide at least one example of a confidence interval and interpret the result.

The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.

Draw the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded.
