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.)

(b) P(x ≥ 43 | μ = 30 and σ = 9) enter the probability of 43 or more outcomes if the mean is 30 and the standard deviation is 9

(c) P(x > 26 | μ = 30 and σ = 5) enter the probability of more than 26 outcomes if the mean is 30 and the standard deviation is 5

(d) P(19 < x < 26 | μ = 25 and σ = 3) enter the probability of more than 19 and fewer than 26 outcomes if the mean is 25 and the standard deviation is 3

(e) P(x ≥ 106 | μ = 90 and σ = 2.87) enter the probability of 106 or more outcomes if the mean is 90 and the standard deviation is 2.87

Answer 1

last answer might be different but I have taken approximate value from chart. Please check it with yourself . If u face any difficulties you can ask me.
