Health experts recommend that runners drink 4 ounces of water every 15 minutes they run.Although handheld bottles work well for many types of runs, all-day cross-country runs requirehip-mounted or over-the-shoulder hydration systems. In addition to carrying more water,hip-mounted or over-the-shoulder hydration systems offer more storage space for food andextra clothing. As the capacity increases, however, the weight and cost of these larger-capacitysystems also increase. The following data show the weight (ounces) and the price for 26 hipmountedor over-the-shoulder hydration systems (Trail Runner Gear Guide, 2003).Model (oz.)

Use these data to develop an estimated regression equation that could be used to predictthe price of a hydration system given its weight.b. Test the significance of the relationship at the .05 level of significance.c. Did the estimated regression equation provide a good fit? Explain.d. Assume that the estimated regression equation developed in part (a) will also apply tohydration systems produced by other companies. Develop a 95% confidence intervalestimate of the price for all hydration systems that weigh 10 ounces.e. Assume that the estimated regression equation developed in part (a) will also apply tohydration systems produced by other companies. Develop a 95% prediction intervalestimate of the price for the Back Draft system produced by Eastern Mountain Sports.The Back Draft system weighs 10 ounces.
