A simple random sample of 10 households, the number of TV's that each household had is as follows:
1,1,2,2.4.4, 1, 3, 5,5
Assume that it is reasonable to believe that the population is approximately normal
and the population standard deviation is 0.40. What is the lower bound of the 95%
confidence interval for the mean number of TV's?
Round your answer to two decimal places (for example: 1.43).
