A healthcare consultant wants to compare the patient satisfaction ratings of two hospitals. Determine a confidence interval for the difference in population means. The results show that for all pairs of distributions the type i (false positive) error rates are very close to the target amounts. Specify the confidence level for the confidence interval, specify the null hypothesis, define the alternative hypothesis, or specify whether you can assume equal variances. The formula is below, and then some discussion. The consultant collects ratings from 20 patients for each of the hospitals.
