Vedmedyk [2.9K]

The z-score of the person who scored 178 on the exam is fund as 2.8.

<h3>What is defined as the normally distribution?</h3>
  • The proper term for just a probability bell curve is the normal distribution.
  • The mean of a normal distribution is zero, as well as the standard deviation is one. It has a skew of 0 and a kurtosis of 3.
  • However all symmetrical distributions are normal, not all normal distributions are symmetrical.
  • Many naturally occurring phenomena resemble the normal distribution.
  • However, most pricing distributions in finance are not perfectly normal.

For the given question,

Mean μ = 150

Standard deviation σ = 10

Observed value x = 178.

The z-score is calculated as;

z = (x - μ)/σ

z = (178 - 150)/10

z = 28/10

z = 2.8

Thus, the z-score of the person who scored 178 on the exam is fund as 2.8.
