- Find three positive geometric means between 2 and 8The 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 α = 0.05, is there enough evidence to say that the Old Farmer’s Almanac figure might no longer be correct? Use the P-value method.What’s the Z0 and Pvalue ?
- What is the z0 and Pvalue ?A polling organization has been hired to conduct a survey to determine the proportion of people who are likely to support an upcoming ballot initiative.
