# Question

According to an American Optometric Association survey, 57% of adults wear eyeglasses as their type of corrective lenses. Suppose we wish to test the null hypothesis “One-half of college students wear eyeglasses” as their type of corrective lenses against the alternative that the proportion is greater than one-half. Let + represent “wear eyeglasses” and - represent “some other corrective lenses or none.” If a random sample of 1500 students is tested, what value of x, the number of the least frequent sign, will be the critical value at the 0.05 level of significance?
