Answer:

The size limit for 15% of of six-year-old trout is 438.52 mm.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 481 millimeters

Standard Deviation, σ = 41 millimeters

We are given that the distribution of mean length of six-year-old rainbow trout is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.15

$P( X < x) = P( z < \displaystyle\frac{x - 481}{41})=0.15$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 481}{41} = -1.036\\\\x = 438.524$

Thus, the size limit for 15% of of six-year-old trout is 438.52 mm.
