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?
- The probability that the child will be between 4.83 and 5.53 years old is
- If such a child is at the 19th percentile, how old is that child? years old.

Step 1

Given uniform distribution with interval (4.73, 5.75) years old

That is (a, b) = (4.73, 5.75) years old

Step 2

1) Mean for this distribution is

Step 3

2) Standard deviation...
