Answer:
251
Step-by-step explanation:
Given -
Mean length of fish =
μ=
73 cm
SD σ
=8 c
m
Number of fish having a length greater than 57 cm out of 480.
Find the value of z at x
=
57

Area between z
=
−
2 and z
= ∞
= Area between z
=
−
1 and z
=
0
+
Area between z
=
0 and z
=
∞
=0.02275+0.5= 0.52275
Therefore number of fish having teeth greater than 57 cm
= 0.52275*480 = 5.2275*48 = 250.92 ≅251
