Question

The age of children in kindergarten on the first day of school is uniformly distributed between 4.73 and 5.75 years old. A first time kindergarten child is selected at random. Round answers to 4 decimal places if possible.

The mean of this distribution is

The standard deviation is

The probability that the the child will be older than 5 years old?

Step 1

Let X be the random variable uniformly distributed between 4.73 and 5.75 seconds.

Denote X as the age of children in kindergarten.

Thus, the probability density function of X is:

Step 2

The mean of the uniform distribution is given by,

Step 3

The standard deviation of the unifo...
