3. Suppose the amount of time government employees spend working on a workday is normally distributed with μ = 8.7 hours and σ = 0.7 hours. Let X be the amount of time (in hours) that a randomly selected government employee works on a workday. Determine the following probabilities and provide support for the standardized values and a visual of the distribution. a. P(X >9) b. P(7 < x < 8) 4. Revisiting question 3, suppose again that amount of time government employees spend working on a workday is normally distributed with μ = 8.7 hours and σ = 0.7 hours. Let X be the mean number of hours worked for a random sample of 9 government employees. Determine the following probability and provide support for the standardized values and a visual of the distribution. a. P(X ≤9)
