A candy company claims that 9% of the jelly beans in its spring mix are pink. Suppose that the candies are packaged at random in small bags containing about 50 jelly beans. A class of students opens several bags, counts the various colors of jelly beans, and calculates the proportion that are pink. Describe the sampling distribution model of the proportion of pink jelly beans in small bags. (a) mean = 9%; standard deviation = 2.02% (b) mean = 9%; standard deviation = 4.05% (c) There is not enough information to describe the distribution (d) mean = 91%; standard deviation = 2.02% (e) mean = 91%; standard deviation = 4.05%
