Answer:
<h2>The standard deviation is 2.6076809621.</h2>
Step-by-step explanation:
The set of values are 2, 4, 7, 8, 9.
The mean of these values are .
The mean of the squares of the differences of these numbers and the mean is .
In order to get the value of the standard deviation, we need to square-root the value of 6.8.
Hence, the standard deviation of the data set is ≅2.6076809621.
Answer:
Predicted value:13.1 residual 0.9
Step-by-step explanation:
this is because if the predicted value is 13.1 the residual or left over 0.9. a simple strategy is subtract the predicted value from the actual value to find the residual.
