Part 2
Is it safe to conclude that the population standard deviation is less than 1.30°F​?
A.
This conclusion is not safe because 1.30°F is outside the confidence interval.
B.
This conclusion is safe because 1.30°F is in the confidence interval.
C.
This conclusion is not safe because 1.30°F is in the confidence interval.
D.
This conclusion is safe because 1.30°F is outside the confidence interval.
