In a study of perception, 146 men are tested and 27 are found to have red/green color blindness.

(a)

Find a 90% confidence interval for the true proportion of men from the sampled population that have this type of color blindness.

confidence interval enter your answer in the form a,b (numbers correct to 3 decimals)

(b)

Using the results from the above mentioned survey, how many men should be sampled to estimate the true proportion of men with this type of color blindness to within 1% with 95% confidence?
