A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. The mean is found to be 11.4 reproductions and the population standard deviation is known to be 2. If a sample of 375 was used for the study, construct the 90% confidence interval for the true mean number of reproductions per hour for the bacteria. Round your answers to one decimal place.
Answers: 3
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
.
, so 
is the standard deviation of the population and n is the size of the sample.
