Answer:
40.7 pounds
Explanation:
Given that:
Mean, m = 40
Standard deviation, σ = 1.3
Weight greater than 30% = 0.3
P(x > Z) = 0.3
Z = (x - m) / σ
P(x > Z) = 0.3
Z = 0.524 ( Z probability calculator)
Hence,
0.524 = (x - 40) / 1.3
0.524 * 1.3 = x - 40
0.6812 = x - 40
x = 0.6812 + 40
x = 40.6812
x = 40.7
Hence, Marlon weighs about 40.7
