2. In a study of perception, 110 men are tested and 24 are found to have red/green color blindness (based on data from USA Today). Assume that this was done in a simple random manner. We want to construct a 95% confidence interval estimate of the proportion of all men with this type of color blindness. a. What is the value of the point estimate, p-hat, for this confidence interval? A. 0.24 В. 24 С. О.22 D. 4.58 b. What is the value of the margin of error for this confidence interval? А. 0.025 В. 0.065 С. 0.003 D. 0.077 c. A 95% confidence interval estimate of the proportion of all men with red/green color blindness was found to be 0.14 to 0.30. If we learn that the actual population proportion of men with red/green colorblindness is equal to 0.12, then what can we conclude? A. The confidence interval was wrong. B. The confidence interval was correct C. We would need to see the sample data to make any conclusions D. None of the above

2. In a study of perception, 110 men are tested and 24 are found to have red/green
color blindness (based on data from USA Today). Assume that this was done in a
simple random manner. We want to construct a 95% confidence interval
estimate of the proportion of all men with this type of color blindness.
a. What is the value of the point estimate, p-hat, for this confidence interval?
A. 0.24
В. 24
С. О.22
D. 4.58
b. What is the value of the margin of error for this confidence interval?
A. 0.025
В. 0.065
C. 0.003
D. 0.077
c. A95% confidence interval estimate of the proportion of all men with
red/green color blindness was found to be 0.14 to 0.30. If we learn that the
actual population proportion of men with red/green colorblindness is equal
to 0.12, then what can we conclude?
A. The confidence interval was wrong.
B. The confidence interval was correct
C. We would need to see the sample data to make any conclusions
D. None of the above
