1. The director of medical services wants to conduct a hypothesis test, using a sample of emergency response times, to determine whether or not the service goal of 12 minutes or less is being achieved. A random sample of 40 emergencies was taken. The average response time was 13.25 minutes with a standard deviation of 3.2 minutes. Conduct the hypothesis test with alpha = 0.05 and draw your conclusion.

Solutions

Expert Solution

We calculate the test statistic using the formula mentioned. The critical value is obtained from STATKEY (image attached for reference). We compare the test statistic with critical value and make the required conclusion.

Claim: the average ’30-Year ROI’ for Business majors is less than for Engineering Majors. a. Will one of the two majors cost more than the other according to the average cost calculated in Week 2 with the sample data? If so, which one? b. Does the hypothesis tests support that one of...
