Question
The lifetime of a certain type of battery is known to be normally distributed with standard deviation o = 22 hours. A sample of 50 batteries had a mean lifetime of 120.1 hours. It is desired to construct a 95% confidence interval for the mean lifetime for this type of battery. Part 1 of 6 (a) What is the point estimate? The point estimate is 120.1 # Part 2 of 6 (b) Find the critical value. Skip Part esc !
