Instructions: Fill in the required information on the blanks provided after each question. Use the t-table provided in the module to solve for critical values. If the test is two-tailed, write '+-' before the values to denotei,e. if the critical values are t=-1.098 and t=1.098, simply write+-1.098. For numerical answer, round up to three decimal places.

1....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 25 people and found that they used on average 125.5 gallons per day and s=7.3. At a=0.05, is there enough evidence to say that the Old Farmer's Almanac figure might no longer be correct?

2....The average college student goes through 750 disposable cups in a year. To raise environmental awareness, a student group at a large university volunteered to help count how many cups were used by students on their campus. A random sample of 50 students' results found that they used a mean of 735 cups with =42 cups. At a=0.10, is there sufficient evidence to conclude that the mean differs from 750?

3.A health researcher read that a 55-kg female can burn an average of 440 calories per hour playing tennis with standard deviation of 10 calories. Thirty-six females were randomly selected and tested. The mean of the number of calories burned per hour was 438.1. Can it be concluded at a=0.05 that the average number of calories burned is less than originally thought?
