Final answer:
To find the actual weight of an animal whose z-score is 1.5, use the formula x = mean + (z * standard deviation). Substituting the given values, the weight is 1277.5 pounds.
Step-by-step explanation:
To find the actual weight of an animal whose z-score is 1.5, we can use the formula:
x = mean + (z * standard deviation)
Given that the mean weight of the group of steers is 1150 pounds with a standard deviation of 85 pounds, and the z-score is 1.5, we can substitute these values into the formula:
x = 1150 + (1.5 * 85)
Simplifying the equation:
x = 1150 + 127.5
x = 1277.5
Therefore, the actual weight of the animal whose z-score is 1.5 is 1277.5 pounds.
