The time ( in number of days) until maturity of a tomato plant is normally distributed with mean mu and standard deviation of 2.

The time ( in number of days) until maturity of a tomato plant is normally distributed with mean mu and standard deviation of 2.4. We select a simple random sample of four plants and measure the time until maturity. The sample yields an average of 65 days. construct a 98% confidence interval for the mean time until maturity of tomato plants. Interpret the interval in context of the problem.
