In one variation of a study conducted by Privitera, Cooper, and Cosco (2012), participants were asked to eat fast or slow, and the amount consumed in their meal was recorded. In this study (M ± SD), participants who ate slowly consumed 627 ± 183 kilocalories; participants who ate fast consumed 670 ± 184 kilocalories. Assuming these data are normally distributed,
(a) In which group, the slow group or the fast group, was it more likely that participants consumed greater than 700 kilocalories in their meal?
(b) In which group, the slow group or the fast group, was it more likely that participants consumed less than 600 kilocalories in their meal?
