Suppose that the foot length of a randomly chosen adult male is a normal random variable with mean μ=11 and standard deviation σ=1.5. With this information complete the following and fill in blanks. 1) a) What is the probability that a randomly chosen adult male will have a foot length between 8 and 14 inches? P(8 < r < 14) = _____ or ______% b) An adult male is almost guaranteed (0.997 probability) to have a foot length between what two values? P(_____< r < ______)= 0.997 2) The probability is only 2.5 % that an adult male will have a foot length greater than h
Suppose that the foot length of a randomly chosen adult male is a normal random variable with mean μ=11 and standard deviation σ=1.5. With this information complete the following and fill in blanks.
1)
a) What is the probability that a randomly chosen adult male will have a foot length between 8 and 14 inches?
P(8 < r < 14) = _____ or ______%
b) An adult male is almost guaranteed (0.997 probability) to have a foot length between what two values?
P(_____< r < ______)= 0.997
2) The probability is only 2.5 % that an adult male will have a foot length greater than how many inches?
P(r > _____) =0.025
3) What is the probability that a randomly selected male will have a foot length between 8 and 12.5 inches?
P(8 < r < 12.5) = _______ or ________%
