Question N1

[T wo-Sample Mean Test when 21 at 22] As an extension to Wednesday' s discussion, what if the two samples have different variance structures. In a large sample problem, we can do the same procedure but with an approximate x2 test. A confidence ellipsoid for pi \"2 is all .111 p2 satisfying 1 1 '1- [X1 '32 (M1 [12)],(11151 + 11252) [X1 "X2 (M1 "M2\" 5 Z1301) Suppose two measurements of power usage for electric car drivers (n1 = 56) and non-electric car drivers (112 = 89).The summary statistics are: X1 [044] '51 = [138.3 238 566 238 731 _ 1300 _ 86.3 196 X2 [3550] '52_[196 560 Find 95% simultaneous confidence intervals for the differences in the mean components and discuss what can be concluded in this test. (6.1) Consider the ethical statistics guidelines laid out by the American Statistical Association. Statistical errors can be technical and sometimes even buried within conventional practices such as taking a statistically significant comparison as strong evidence in favor of a favored hypothesis. How would you report the result of N1 when the results were not in your favor? Analyze your ethical decision made from the Christian worldview
