An optometrist wishes to know the proportion of patients who undergo laser eye surgery who end up with 20/20 vision or better following the surgery. If the optometrist wishes to achieve an accuracy within 0.05 at the 2% level of significance, what size sample is required if there is NO preliminary notion of the true proportion for this study?
