Question
Hi, I need help with question # 23. The given information is on top. Thanks in advance.
Use the following to answer questions 20 – 23.
A researcher is interested in the lengths of Salvelinus fontinalis (brook trout), which are known to be
approximately normally distributed with mean 80 centimeters and standard deviation 5 centimeters. To
help preserve brook trout populations, some regulatory standards need to be set limiting the size of fish
that can be caught.
20. The probability of catching a brook trout less than 72 centimeters in length is
@0.0548.
b. 0.3745.
c. 0.6255.
d. 0.9452
21. What proportion of fish are larger than 86 centimeters in length?
a. 0.0228
b. 0.0548
с..1151
d. 0.8849

22. To ensure that the shortest 8% of the brook trout get thrown back the lower cutoff should be set at
a. 72.95 centimeters.
b. 75.00 centimeters.
c. 80.00 centimeters.
(d 87.03 centimeters.
