2. a. A shipment of 1000 small lab mice arrives at the animal care facility with the weight following a skewed distribution (μ=?,σ=2.5). A sample of 40 mice is selected and weighed. The sample average weight is 10.2 g, and the sample standard deviation is 2 g.
In order to find a 90% confidence interval for the mean weight of all the mice in the shipment:
-The margin error is?
-The 90% confidence interval is ?
