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")”

Please drow Flow chart
The program you will be writing displays a weekly payroll
report. A loop in the program should ask the user for the
employee’s number, employee’s last name, number of hours worked,
hourly pay rate, state tax, and federal tax rate. After the data is
entered and the user hits the enter key, the program will calculate
gross and net pay then displays employee’s payroll information as
follows and asks for the next employees’ information. if the...
