IB Statistics and Probability Problem 010
The weights of children in a group are normally distributed with a mean of \(22.5 kg\) and a standard deviation of \(2.2 kg\).
Write down the probability that a randomly chosen child has a weight greater than \(25.8 kg\).
\(95{\%}\) of the children in this group weigh less than \(k\) kilograms. Find the value of \(k\).
The figure below shows a normal curve.
On this figure, shade the region that represents the following information:
\(87{\%}\) of the children weigh less than \(25 kg\).
