Researchers investigated the effects of being distracted by a game on how much people eat. The 22 patients in the treatment group who ate their lunch while playing solitaire were asked standard deviation of 1.9. The averaqe o do a serial-order recall of the food lunch items they ate. The average number of items recalled by the patients in this group was 4.9, with humber of items recalled by the patients in the control group (no distraction) was 6.2, with a standard deviation of 1.9. Do these data provide strong evidence that the average number of ood items recalled by the patients in the treatment and control groups are different? (Use a significance level of 0.05. Use µ, - Hc.) State the appropriate null and alternative hypotheses.
