Prepare Your Statistical Procedure Based on the information in each part, you will first identify which type of procedure will be performed ~ a confidence interval or a hypothesis test. Then, determine which method is appropriate for comparing the two population means ~ the Pooled Method or the General (Unpooled or Welch's) Method. Question 3 Subquestions 3.a TBD points A researcher wants to estimate the difference in running speed for a mile for two groups of college athletes: short distance runners and long distance runners. They record the time it takes for a random sample of 17 short distance runners to run a mile, and the time it takes for a random sample of 42 long distance runners to run a mile. Let group 1 be the long distance runners and group 2 be the short distance runners. 1. Which type of procedure should be performed ~ a confidence interval or a hypothesis test? 2. If a confidence interval, define what the parameter of interest is in context. If a hypothesis test, what should our hypotheses be.
