You have data set withn = You add one value to the data set, x10 9 values and a mean of = 31. 42. ¿What is the mean of the expanded data set?

Explain MEAN SQUARES (M S) AND F RATIOS.

The scatterplot below shows the mean cost of an oil change for Sadie's car during each of the last 10 years. Mean Cost of Oil Change Mean Cost (dollars) 000 25 A 20 B 15 Year Using the points (2, 15) and (7, 21), what is the best estimate of what the mean cost of an oil change willbe car for Sadie's car when it is 12 years old? 10 ➤X 0 1 2 3 4 5 6 7 8 9 10 Response 3* $25 III $27 C $29 40 $31 3 points

A. Determine the coefficient of​ determination, r2​, and interpret its meaning. (Fill in the Blank) r2 = ___? ​(Round to four decimal places as​ needed.) B.  What is the meaning of the coefficient of​determination? (Choose Below) A. It measures the variability in the actual plate gap from the predicted plate gap. B. It measures the variability in the actual tear rating from the predicted tear rating. C. It is the proportion of the variation in the plate gap that is explained by the variability in the tear rating. D. It is the proportion of the variation in the tear rating that is explained by the variability in the plate gap. C. Determine the standard error of the estimate. SYX = ___? ​(Round to four decimal places as​needed.)

prove that If we multiply the data values by a constant (say, c), value of geometric mean will be affected. how this will affect the geometric mean? Use the equation in image to prove it, and give an example.

Describe about MEAN SQUARE (M S ) AND THE F RATIO.

The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude? Standard deviation CV = • 100% Mean E Click the icon to view the data sets.
