a. Develop a scatter plot with income as the dependent variable
and age as the independent variable. Include the estimated
regression equation and the coefficient of determination on your
scatter plot. Briefly comment on the relationship between the two
variables, and fully interpret the coefficient of determination. b.
Using the Excel’s Regression Tool, develop the estimated regression
equation to show how income (y annual income in $1000s) is related

Please finish the following assignment in Excel.
Ignoring price, create a chart that displays the seasonality of
cranberry sales.
Ignoring price, create a chart that shows whether there is an
upward trend in sales.
Determine average sales per quarter, breaking it down based on
whether your price was higher or lower than the competitor’s price.
You can use the following function to transform the price into a
category variable: “=IF(J14<K14,"Higher Price",
"Lower Price")”
