Question

Calculate the probabilities for each of the following problems. Round all answers to four decimal places.

1) For a distribution with µ = 845.9; σ = 46.8; n = 60, what is the probability of randomly selecting a value less than 835?

2) For a distribution with µ = 23.7; σ = 4.5; n = 30, what is the probability of randomly selecting a value less than 22?

3) For a distribution with µ = 1272.5; σ = 145.2; n = 100, what is the probability of randomly selecting a value more than 1290?

4) For a distribution with µ = .024; σ = .003; n = 45, what is the probability of randomly selecting a value more than .025?
