Use data set mosquitoes.txt Download mosquitoes.txt. Researchers were interested in determining whether or not drinking beer (treatment) influenced attractiveness to mosquitoes with respect to simply drinking water (control). They opened a container holding 50 mosquitoes next to each of 25 alcohol-free participants and measured the proportion of mosquitoes that left the container and flew toward the participants (they called this proportion the "activation"). They repeated this procedure 15 minutes after each of the same participants had consumed a liter of beer and measured the "change in activation" (after minus before). This procedure was also carried out on another 18 humans participants who were given water instead of beer. The change in activation of mosquitoes is given for both the beer-and water-drinking groups. Provide the p-value for this test (rounding to 3 decimals is required):
