Question

Assume a normal distribution and find the following probabilities.

(Round the values of z to 2 decimal places. Round your answers to 4 decimal places.)

(a) P(x < 17 | μ = 21 and σ = 3)
enter the probability of fewer than 17 outcomes if the mean is 21 and the standard deviation is 3

(b) P(x ≥ 76 | μ = 60 and σ = 9)
enter the probability of 76 or more outcomes if the mean is 60 and the standard deviation is 9

(c) P(x > 56 | μ = 60 and σ = 5)
enter the probability of more than 56 outcomes if the mean is 60 and the standard deviation is 5

(d) P(17 < x < 20 | μ = 19 and σ = 3)
enter the probability of more than 17 and fewer than 20 outcomes if the mean is 19 and the standard deviation is 3

(e) P(x ≥ 94 | μ = 80 and σ = 2.88)
enter the probability of 94 or more outcomes if the mean is 80 and the standard deviation is 2.88
