Answer:
0.6069
Step-by-step explanation:
Given an approximately normal distribution:
Z = (x - mean) / standard deviation
Mean = 69.3 ; Standard deviation = 2.58
For :
P(x < 70)
Z = (70 - 69.3) / 2.58
Z = 0.7 / 2.58
Z = 0.2713
P(Z < 0.2713) = 0.6069
F(3) means x =3 and x = 3 > -1 (f(x) = x^2 if x > -1)
so
f(3) = x^2 = 3^2 = 9
Answer
