For each hypothesis test, you must state (a) hypotheses, (b) test statistic, p-value, (c) rejection rule, and (d) both parts of the conclusion. It is only necessary to calculate the effect size if the problem calls for it. Use a .05 level of significance for all hypothesis tests. Use StatCrunch to complete all hypothesis tests and confidence intervals. Make sure you copy and paste the relevant output for the solutions

  1. (10 points) In a sample of 100 people who do not have health insurance, the mean number of doctor visits in the past year was 1.85 with a standard deviation of .4. In a sample of 100 people who do have health insurance, the mean number of doctor visits in the past year was 1.98 with a standard deviation of .5.
