Suppose a candidate running for sheriff in a rural community claims that she will reduce the average speed of emergency response to less than 30 minutes, which is thought to be the average response time with the current sheriff. There are no past records; so the actual standard deviation of such response times cannot be determined. Thanks to this campaign, she is elected sheriff, and careful records are now kept. The response times (in minutes) for the first month are: 26, 31, 27, 30, 25, 29, 31, 36, 24, and 23 . Using the 0.05 level of significance, did she keep her promise? 1. State the null with appropriate symbol. 2. State the research hypothesis with approp. Symbol. 3. Determine the cutoff sample score or cv 4. Determine the sample score. 5. Decide whether to reject the null. Write out your response in this discussion board
