A random sample of n = 100 observations is selected from a population with µ = 29 and o=25. Approximate the
probabilities shown below.
b. P(22.1 ≤x≤26.8)
d. P(x ≥ 27.0)
Click the icon to view the table of normal curve areas.
a. P(x ≥ 28)
c. P(x ≤28.2)
a. P(x ≥28) = 0.655 (Round to three decimal places as needed.)
b. P(22.1 ≤x≤26.8) = 0.187 (Round to three decimal places as needed.)
c. P(x≤28.2) = 0.374 (Round to three decimal places as needed.)
d. P(x ≥ 27.0) = 0.788 (Round to three decimal places as needed.)
