The time (in number of days) until maturity of a certain variety of tomato plant is Normally distributed with unknown mean ?. I select a simple random sample of 5 plants of this variety and measure the time until maturity. The sample yields sample mean of 65 days and sample standard deviation of 2.4 days. Construct a 95% confidence interval for ? in days? Write your answer in 1 decimal. ( , )

The time (in number of days) until maturity of a certain variety of tomato plant is normally distributed with an unknown mean. Select a simple random sample of n plants of this variety and measure the time until maturity. The sample yields a sample mean of 65 days and a sample standard deviation of 2 days. Construct a 95% confidence interval for μ in days?

The time (in number of days) until maturity of a certain variety of tomato plant is Normally distributed with unknown mean μ. I select a simple random sample of 10 plants of this variety and measure the time until maturity. The sample yields sample mean of 65 days and sample standard deviation of 2.4 days. Construct a 95% confidence interval for μ in days? Write your answer in 1 decimal.
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.
