Answer: 149

Step-by-step explanation:

out of 80 students, 20 said that they prefers cats, then the relative frequency is:

p = 20/80 = 0.25

then, out of the 597 students a estimate of:

N = 0.25*597 = 149.25 like cats

We should round it down so we have a whole number, then we have a estimate of 149 students.
