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). Based on the 99% confidence interval, can we conclude there is significant evidence at the α=0.01 significance level that there is a difference in the after treatment and before treatment REM sleep time? Group of answer choices Yes, since 0 is in the interval.

Question
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).
Based on the 99% confidence interval, can we conclude there is significant evidence at the α=0.01 significance level that there is a difference in the after treatment and before treatment REM sleep time?
Group of answer choices
Yes, since 0 is in the interval.
Yes, since 0 is not in the interval.
No, since 0 is in the interval.
No, since 0 is not in the interval.
No, since we do not have the relevant information (such as p-value)
