Assume that a set of test scores is normally distributed with a mean of 70 and a standard deviation of 10. In what percentile is
vlabodo [156]
Given:
μ = 70, the mean
σ = 10, the standard deviation

The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5

From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.

This histogram is skewed to the left and its distribution's center would be three (3).

<h3>What is a histogram?</h3>

A histogram is used to graphically represent a set of data points into user-specified ranges, especially through the use of rectangular bars.

In this scenario, we can infer the following about the histogram distribution's center, spread, and overall shape:

  • This histogram is skewed to the left.
  • Its distribution's center would be three (3).
  • The spread implies that more students are between 58-59 and 60-61 inches.
  • The shape shows that many of the values are at the lower end.
