On this worksheet, make an XY scatter plot linked to the following data:

X 22 48 37 30 24 10 42 30 41 29 16 36 45 11 31 26 31 33 46 22 13 22 32 49 35

Y 3872 9312 5217 4230 4536 1820 8274 121 6314 3828 2448 6156 7515 1309 3534 4576 5797 4983 6670 2464 2197 3278 5408 7497 5705

Add trendline, regression equation and r squared to the plot. Add this title. ("Scatterplot of X and Y Data")

The scatterplot reveals a point outside the point pattern.

Copy the data to a new location in the worksheet. You now have 2 sets of data.

Data that are more tha 1.5 IQR below Q1 or more than 1.5 IQR above Q3 are considered outliers and must be investigated.

It was determined that the outlying point resulted from data entry error. Remove the outlier in the copy of the data.

Make a new scatterplot linked to the cleaned data without the outlier, and add title ("Scatterplot without Outlier,")trendline, and regression equation label. Compare the regression equations of the two plots. How did removal of the outlier affect the slope and R²?
