Construct a 90% confidence interval for the difference of means between the mice that did not receive the steroids and the mice that did receive the steroids. Show all organized work as done in the videos and box your answer. Explain how you get the t-score for 90% CI. b. Interpret the confidence interval in context of the problem. c. Can we conclude that there is an improvement in the mice that had the steroid cream, compared to those th not? Clearly answer "yes" or "no" and then explain your answer.
