the Old Farmer’s Almanac stated that the average consumption of water per person per day was 123 gallons. To test the hypothesis that this figure may no longer be true, a researcher randomly selected 16 people and found that they used on average 119 gallons per day and s = 5.3. at a = 0.05, is there enough evidence to say that the Old Farmer’s Almanac figure might no longer be correct?
