Can anyone put some explanation about questions 17 to 21... I tried to solve it, but didn't get any results that seemed ok (they all seemed absurd to me)... and all were far from these.
How did you put the tables do calculate?
1.The treatment does something.
9.The average blood pressure in the population is 120 mm.
14.at all private universities in the state.
15.NA (that is, unknown based on the given information)
16.probability histogram of the average number of hours worked in the week before the survey by a simple random sample of 1000 freshmen taken from private universities in the state
22.support the statistician’s belief.
