Answer:
New mean will be 12
And no change in standard deviation
Step-by-step explanation:
We know the relationship between the two mean and standard deviation


If we add 2 to each value of x that means the mean will become n will become 2n and since we are adding 2 to each value
The new mean will become 12
And there will be no change in the standard deviation because of equal change in the each data.
Answer:
Option D (Yes. The model is a good fit because the residual plot does not have a random pattern).
Step-by-step explanation:
First of all, insert all the data in Microsoft Excel. Make sure that the values of X are in the ascending order. Then, make the scatter plot of the data with the line of best fit from the Insert option. The graph shows that there is a positive relation between x and y. Most of the actual values of y lie very close to the line. A very few observations are a little further from the line of best fit. Therefore, the model is a good fit because the residual plot does not have a random pattern. Option D is the correct answer!!!
