A researcher asked participants to wear a simple counting device for a week and they counted the number of times that they thought about food.2 Determine a point estimate of the daily mean number of times a person thinks about food and the (1 - a )% error margin separately for males and females.
(a) Female n = 36 = 11.49
s = 9.97 1 - α = .95
(b) Male n = 29 = 24.49
s = 23.16 1 - α = .95
