Answer with explanation:</h2>
Given : The distribution of the lengths of a commercially caught fish is bell-shapped ( i.e. normally distributed ) with and .
Let x be the length of a commercially caught fish .
Any fish measuring less than 20 cm must be released.
1) The probability that a fish measuring less than 20 cm :
∴ The proportion of fish that must be released is about 0.16.
2) The probability that a fish measuring between 20 cm and 32 cm :
If total 500 fish are caught, then number of fish have lengths between 20 cm and 32 cm = 0.8185 x (500)=409.25 ≈409
The nearest option from the given options is "408".
