Question

The average weight of adult male bison in a particular federal wildlife preserve is 1450 pounds with a standard deviation of 240 pounds. Find the weight of an adult bull whose is z-score 1.5.

Answer 1

Explanation:

To find the weight of an adult bull whose z-score is 1.5, we need to use the formula:

z = (x - μ) / σ

where z is the z-score, x is the weight of the bull we want to find, μ is the population mean weight (1450 pounds), and σ is the population standard deviation (240 pounds).

We can rearrange this formula to solve for x:

x = z*σ + μ

Substituting the given values, we get:

x = 1.5 * 240 + 1450

x = 360 + 1450

x = 1810

Therefore, the weight of an adult bull whose z-score is 1.5 is 1810 pounds.
