You have found the following ages (in years) of all 666 lions at your local zoo: 13,2,1,5,2,7 What is the average age of the lions at your zoo? What is the standard deviation? Average age: years old Standard deviation: years

We want to find the mean or average and the standard deviation of the given set.

The average age is 5 years old and the standard deviation is 4.52 years old.

We know that for a general set of N elements {x₁, x₂, ..., xₙ} the average or mean is given by:

And the standard deviation is given by:

The given set is:

{13, 2, 1, 5, 2, 7}

Now we just need to use the two given formulas for our set.

The mean is:

And the standard deviation is:

So the average age is 5 years old and the standard deviation is 4.52 years old.

Step-by-step explanation:

Given

Number of Lions, n: 6

Ages: 13, 2, 1, 5, 2, 7

Required

Determine the:

1. Mean

2. Standard Deviation

Mean is calculated as;

Standard Deviation is calculated as follows

Where Mx represent mean

Substitute values for x, Mean and Land

The mean and standard deviation is 5 and 4.123 respectively

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
