Assume that 26% of students at a university wear contact lenses. We randomly pick 300 students. Describe the sampling distribution model of the proportion of students in this group who wear contact lenses.
A) there is not enough infoB) mean=26% standard error= 2.5%C) mean= 26% standard error= 1.1%D) mean= 74% standard error= 2.5%E) mean= 74% standard error= 1.1%
