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 ? b.
