A team of researchers aims to understand whether a sleep treatment drug has an effect on the number of hours of REM sleep. Five subjects were randomly selected and their time in REM sleep (in minutes) was measured before treatment and after treatment. The before treatment measurements are: (30, 45, 90, 60, 100). The after-treatment measurements for the same five patients are: (35, 30, 80, 70, 110). Your boss looks at the confidence interval you computed and says that it is too wide to be useful for decision making. You propose a list of changes to your methodology that may result in a narrower interval. Which option should NOT be on your list: Group of answer choices increase the confidence level recruit more subjects into the study decrease the confidence level
