Question

Find the mean for the following observations:

6, 7, 1, 0, 6.

a) 4
b) 5
c) 6
d) 20

Answer 1

To calculate the mean for the observations 6, 7, 1, 0, 6, we add them to get 20, then divide by the count of numbers, which is 5. The mean is 4. The sample mean is therefore 4, which corresponds to option (a).

Step-by-step explanation:

To find the mean of the following observations: 6, 7, 1, 0, 6, you would add up all the numbers and then divide by the count of numbers. Here is how you calculate it:

• Add all the observations together: 6 + 7 + 1 + 0 + 6 = 20.
• Count the number of observations: 5.
• Divide the sum of the observations by the count: 20 ÷ 5 = 4.

The sample mean is therefore 4, which corresponds to option (a).

To find the mean of the given observations, you need to add up all the numbers and divide the sum by the total number of observations. In this case, the observations are 6, 7, 1, 0, and 6.

The sum of these numbers is 20 (6 + 7 + 1 + 0 + 6). Since there are 5 observations, divide 20 by 5 to find the mean. Therefore, the mean is 4 (20 ÷ 5 = 4).
