Question

The weight of a Great blue heron, a type of bird, can grow to around 4 pounds, but can vary. Let W be a random variable that represents the weight of a Great blue heron. The probability density function of W is given below. Move the left and right sliders so that the area of the blue shaded region represents the probability that a Great blue heron is at least 9 pounds, but no more than 10 pounds.

Answer 1

10 ≥ w ≥ 9 ( ? )

Explanation:

the probability that a Great blue heron is at least 9 pounds, but no more than 10 pounds -> w= weight of great blue heron

w is at lest 9 pound's -> w ≥ 9

w is no more than 10 pound's -> w ≥ 10

w ≥ 9 ( + ) w ≥ 10 = 10 ≥ w ≥ 9
