(b) What is the mean number of nutrition-conscious people in your sample if p = 0.4 is true? What is the probability that X lies between 75 and 85? (c) You and 100 of your 200 respondents concerned about nutrition. Is this reason to believe that the percent in your area is higher than the national 40%?
