Mean of 5 observations:
The given problem states that the mean of 5 observations, x, x+2, x+4, x+6, and x+8, is 11. We need to find the value of x.
Step 1: Set up the equation:
To find the value of x, we can start by finding the sum of these 5 observations. The mean of these observations is equal to the sum divided by the number of observations. So, we can set up the equation as follows:
(x + (x+2) + (x+4) + (x+6) + (x+8)) / 5 = 11
Step 2: Simplify the equation:
Let's simplify the equation by combining like terms and solving for x:
(5x + 20) / 5 = 11
5x + 20 = 55
5x = 55 - 20
5x = 35
Step 3: Solve for x:
Dividing both sides of the equation by 5, we can find the value of x:
x = 35 / 5
x = 7
Conclusion:
The value of x is 7.
