A campus representative for a website wants to know what percentage of students at a large state campus currently wear contact lens. Suppose the true proportion is 31%. Complete parts a and b. a) We randomly picked 90 students. Let p represent the proportion of students in this sample who wear contacts. What's the appropriate model for the distribution of p? Specify the name of the distribution, the mean, and the standard deviation. Be sure to verify that the conditions are met. The distribution is a v distribution. The mean is (Type an integer or a decimal. Do not round.) The standard deviation is. (Round to three decimal places as needed.) What assumptions underlie your model? Are the conditions met? O A. The randomization condition, 10% condition, and success/failure condition are met or can be assumed to be correct. O B. The 10% and success/failure conditions are not met. The randomization condition is met or can be assumed to be correct. OC. The success/failure condition is not met. The randomization condition and 10% condition are met or can be assumed to be correct. O D. The randomization condition is not met. The success/failure condition and 10% condition are met. O E. The randomization and 10% conditions are not met. The success/failure condition is met or can be assumed to be correct. O F. The randomization and success/failure conditions are not met. The 10% condition is met or can be assumed to be correct. O G. The 10% condition is not met. The randomization condition and success/failure condition are met or can be assumed to be correct. O H. Without unreasonable assumptions, none of the conditions are met. b) What's the approximate probability that more than 33% of this sample wear contacts? The probability is (Round to three decimal places as needed.)
