How do I find the degrees of freedom? Gaming and distracted eating, Part I: A group of researchers are interested in the possible effects ofdistracting stimuli during eating, such as an increase or decrease in the amount of food consumption. Totest this hypothesis, they monitored food intake for a group of 44 patients who were randomized into twoequal groups. The treatment group ate lunch while playing solitaire, and the control group ate lunchwithout any added distractions. Patients in the treatment group ate 52.1 grams of biscuits, with a standarddeviation of 45.1 grams, and patients in the control group ate 27.1 grams of biscuits, with a standarddeviation of 26.4 grams. Do these data provide convincing evidence that the average food intake(measured in amount of biscuits consumed) is different for the patients in the treatment group? Assumethat conditions for inference are satisfied. Use the treatment group as Group A and the control group asGroup B.What are the hypotheses for this test?O Ho: Hno distraction = HdistractionHa: Hno distraction < HdistractionOO Ho: Pno distraction = HdistractionHa: Hno distraction > HdistractionHo: Hno distraction = HdistractionHa: Hno distraction distractionThe degrees of freedom associated with this test are: 42XThe test statistic for the hypothesis test is (round your answer to 3 decimal places):2.240°The p-value for the hypothesis test is:O between .02 and .025O between .01 and .02Obetween .02 and .04O between .04 and .05Interpret the result of the hypothesis test in the context of the study:O Since p < a we have enough evidence to reject the idea that the average biscuit consumption in thetwo groups was the same; our data supports the alternative that distracted eaters will eat more thannon-distracted eaters, on averageO Since p < a we have enough evidence to accept the idea that the average biscuit consumption in thetwo groups was the sameSince p < a we have enough evidence to reject the idea that the average biscuit consumption in thetwo groups was the same; our data supports the alternative that distracted eaters will eat a differentamount than non-distracted eaters, on averageO Since p < a we do not have enough evidence to reject the idea that the average biscuit consumptionin the two groups was the same
