Question

Let Y = e^x where X is normally distributed with μ = 3.4 and σ = 0.7. Compute the following values. [You may find it useful to reference the z table.]

a. Compute P(Y ≤ 10.4). (Round your intermediate calculations to at least 4 decimal places, “z” value to 2 decimal places, and final answer to 4 decimal places.)

b. Compute P(9.1 < Y < 10.3). (Leave no cells blank - be certain to enter "0" wherever required. Round your intermediate calculations to at least 4 decimal places, “z” value to 2 decimal places, and final answer to 4 decimal places.)

c. Compute the 80th percentile of Y. (Round your intermediate calculations to at least 4 decimal places, “z” value to 3 decimal places, and final answer to the nearest whole number.)
