Ever 2.2 lbs is 1kg, so to find how many kg in 50 lb you would divide 50 by 2.2. 50lbs is equivalent to 22.72 kg.
Answer:
The probability is 0.003907
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD
mean = 506, SD = 115 , x = 200
z-score = (200-506)/115 = -2.66
The probability we want to calculate is;
P( x < -2.66)
we can use the standard normal distribution for this;
P(x < -2.66) is ) = 0.003907
