(Problems 1-2) Taxes and Soda Consumption - Suppose that a sales tax on soda will be removed in a random sample of communities to measure the impact on soda consumption. We wish to determine whether average per-capita consumption of untaxed soda is greater than 50 gallons a year. 1. Write the hypotheses using words. H: H: aIn an experiment to compare the quality of four different brands of magnetic recording tape, five 2400-ft reels of each brand (A-D) were selected and the number of flaws in each reel was determined.
