Need an explanation on which test this is.

e. A psychiatrist is interested in whether a new drug in development for treating sleep disorders increases the intensity of dreams. One group of participants will sleep in a lab hooked up to an electroencephalogram (EEG) to measure the intensity of brain activity during sleep. Study participants complete two research sessions. During the rst baseline session they sleep without the medication. During the second testing session, participants take the sleep medication. The intensity of participant's brain activity during sleep is measured during both sessions via EEG. Which NHST would the psychiatrist use to determine if the intensity of brain activity increased from the baseline to the testing session? In a sentence, briey explain why this is the appropriate test
