The median for a set of numbers would be the one that appears closest to the middle of the set.
For the set 4, 8, 10, 5, 9, in order to find the median, we must first sort them numerically.
4, 5, 8, 9, 10
Now, which of these 5 numbers is the closest to the middle?
The answer to that would be 8, since it is actually the number in the middle.
The median number for the numbers 4, 8, 10, 5, 9 is 8.
Hope that helped =)

Answer:
answer: At age 71.78 86% of the payments of the plan participants will be ceased
Step-by-step explanation:
Let X be the age at which a person dies. We know that X has a normal distribution with mean 68 and standard deviation 3.5. REcall that the expression P(X<=x) means the probability that a person dies before the age x. In order for us to do the calculations, we consider the random variable Z = (X-68)/3.5. The variable Z will be normally distributed with mean 0 and standard deviation 1 (i.e will be a standard normal distribution). Based on that, we would like to calculate the Z value for which we have 86% of the curve on the left of the value. Using a standard normal distribution table, we can find the z value corresponding to the 86% of the curve, which is aproximately 1.08. Then, the age we are looking for is 1.08*3.5+68 = 71.78 years
