Assume that 26% of students at a university wear glasses. Suppose 300 students are randomly selected. What are the mean and standard deviation of the sampling distribution for the proportion of students in this sample who wear glasses? mean = 0.09; standard deviation = 0.025 O mean = 0.26; standard deviation = 0.025 O mean = 0.26; standard deviation = 0.050 O The values cannot be determined from the information given.
