\f\fConsider a national car rental company that is interested in testing whether there is a difference in mean mileage for SUVs driven in town versus those driven on the highway. Based on its experience with regular automobiles, the company believes the mean highway mileage will exceed city mileage. The company randomly selected 25 SUV rentals driven only on the highway and another 25 SUVs only driven in the city. The vehicles were filled with 14 gallons of gasoline. Each customer then drove around until they ran out of gasoline. The elapsed miles were noted, and the results are found in the mileage file. Steps 1. Specify population parameter of interest and state the null & alt hypotheses a. Ho: H: 2. State level of significance 3. Select random samples from each population 4. Test hypotheses Step 5.1: Decision (Reject Ho vs Do not Reject Ho]: Step 5.2: Write up the decision and conclusion based on business implication (use the complete sentences):The Stanford-Binet IQ test is nationally normed with a mean of 100 and a standard deviation of 15. A principal in an elementary school believes that her students have above-average intelligence and wants verification of her belief. She randomly selects 20 students and checks the student files. You will use as z-test to determine whether the students in this school have above-average intelligence and will summarize your findings in a report. Steps 1. Specify population parameter of interest and state the null & alt hypotheses a. Ho: 2. State level of significance 3. Select random samples from each population 4.
