Proportions In a study of color perception, 132 men are tested, and 48 are found to have red/green color blindness. 1. np (1 – p)= 2. p= 3. Is np(1 p) ≥ 10 ?( yes or no) 4. The margin of error is use the 95% confidence level 5. Construct a 95 % confidence interval for the percent of men in general population who are color blind. Lower Bound Upper Bound
