We are curious to see if college students get less sleep than the average person. It is known from previous studies that the average person gets 8 hours of sleep on average with a standard deviation of 1 hour. We surveyed 100 students from  LTCC and found that on average they got 7.5 hours of sleep with a standard deviation of 1.5 hours.   b) Which of the following is the appropriate calculation for the test statistic? Group of answer choices T= (7.5-8)/(1/sqrt(99)) T = (7.5-8)/(1.5/sqrt(99)) Z = (7.5-8)/(1/sqrt(100)) Z = (7.5-8)/(1.5/sqrt(100))

12.  We are curious to see if college students get less sleep than the average person. It is known from previous studies that the average person gets 8 hours of sleep on average with a standard deviation of 1 hour. We surveyed 100 students from  LTCC and found that on average they got 7.5 hours of sleep with a standard deviation of 1.5 hours.

 

b) Which of the following is the appropriate calculation for the test statistic?

Group of answer choices
T= (7.5-8)/(1/sqrt(99))
T = (7.5-8)/(1.5/sqrt(99))
Z = (7.5-8)/(1/sqrt(100))
Z = (7.5-8)/(1.5/sqrt(100))
