Question

The scores of a certain section is normally distributed with a mean of 30 and a standard deviation of 7. Find the corresponding score of a student given the area of probability.

Between 0 and z is 0.4332

Answer 1

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.
