A normal distribution is observed from the number of rentals per week for a certain car rental company. If the mean is 15 rental
dexar [7]

The probability that on a randomly selected week, the car company rented greater than 24 rentals  is 0.4987

First, we need to calculate the z-score using the formula;

z=\frac{x-\mu}{\sigma} \\

where:

  • \mu is the mean value = 15
  • \sigma is the standard deviation = 3
  • x = 24

Substitute the given values into the formula to get the z-score

z=\frac{24-15}{3} \\z=\frac{9}{3} \\z=3.000

Checking the probability table for P(x > 3.000), the probability that on a randomly selected week, the car company rented greater than 24 rentals

is 0.4987
