Question

4.8,7.1,5.5,4.6 What is the mean value of the data set shown above?

Answer 1

To find the mean value of the data set 4.8, 7.1, 5.5, 4.6, you add the numbers to get a sum of 22.0 and then divide that sum by the number of values, which is 4. The mean value is found to be 5.5.

Step-by-step explanation:

To calculate the mean value of the data set 4.8, 7.1, 5.5, 4.6, you need to follow these steps:

1. Add all the numbers together to get the sum.
2. Divide the sum by the number of values in the data set.

Let's do the calculation step-by-step:

1. Sum = 4.8 + 7.1 + 5.5 + 4.6 = 22.0
2. There are 4 values in the data set.
3. Mean = Sum ÷ Number of values = 22.0 ÷ 4 = 5.5
4. Therefore, the mean value of the data set is 5.5.
