Answer 1

To make a scatter plot of the given data, identify the outlier, and find the regression equation without the outlier.

Step-by-step explanation:

To make a scatter plot of the given data, we plot each data point as an ordered pair (x, y). Here is the scatter plot:

From the scatter plot, we can see that the point (65, 175) is outside of the range defined by the lines Y2 and Y3, making it an outlier.

To find the regression equation for the data set without the outlier, we can use the remaining 10 points. Using the LinRegTTest function on a calculator, we get the equation y = 355.19 + 7.39x.
