Find each of the probabilities where z is a z-score from a
standard normal distribution with
a mean of μ=0 and standard deviation σ=1. Make sure you
draw a picture of each problem. Show all steps

1. For a standard normal distribution, determine the z-score,
z0, such that P(z < z0) = 0.9698.
2. From a normal distribution with μμ = 76 and σσ = 5.9, samples
of size 46 are chosen to create a sampling distribution. In the
sampling distribution determine P(74.399 < ¯xx¯ <
78.079).
