Question

The reported rate for colorblindness for men ages 65 and older is 12%. Assume this estimate is the true population proportion of men ages 65 and older. A SRS of 25 men ages 65 and older is taken. Calculate the probability that proportion of men ages 65 and older who have colorblindness is more than 0.10.

A. 3783

B. 6217

C. This can’t be done because np is not greater than

D. This can’t be done because n is not greater than 30 and we are not told that the variable is normally distributed.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
