If has a normal distribution with and , then the probability can be expressed in terms of a standard normal variable  as:

Which of the following teams consist of employees assigned to work on a specific task in addition to normal work duties?

Which of these factors is considered a compensable factor by compensation professionals?

Which of the following shifts in workforce composition makes it necessary to have a strategic approach to compensation issues?

A hospital finds that 30% of its accounts are at least 60 days in arrears. A random sample of 500 accounts was taken. Let’s define a random variable that represents the number of accounts at least 60 days in arrears in the sample of 500 accounts. Suppose that you are interested to approximate the probability that 100 accounts in the sample were at least 60 days in arrears using the normal distribution. What is the mean and the standard deviation of the normal distribution you would use for the approximation?

Exhibit 2 Banana Republic Factory is a well-known clothing brand in the U.S., and its online mall is also very popular. Because the online mall allows free shipping on orders starting from $50, 75% of all the orders placed through the online mall has the size of $50 or greater ($50+). Assume that a random sample of 28 orders is taken.

Refer to Exhibit 3. How is the probability that a college student sleeps less than 6 hours on a weeknight compared to the probability that a college student sleeps more than 8 hours on a weeknight?

Refer to Exhibit 3. Which of the following Excel function can be used to find the hours of sleep that 80 percent of the students cannot achieve on a weeknight? (Hint: Find  such that )

Let’s assume that  and  are two normally distributed random variables with respective values of the mean,

Refer to Exhibit 2. Which of the following Excel functions would you use to calculate the probability of having 12 or more female Uber drivers in a sample of 25 Uber trips?
