A company that manufacture car batteries tested the average lifetime of their car batteries and found the following results in days. 3050, 2820, 2960, 2700, 2775, 3000, 2905, 2800, 2500, 2750. Find the mean, median, and standard deviation of the lifetime of the car batteries. State the type of distribution you would use to estimate the 95% confidence interval on the mean and then calculate the value?

Answer 1

Hence, we will use the "Normal Distribution" to estimate 95% confidence interval on the mean.
