The numbers below show salmon population’s decrease since 1960. salmon = {{0, 10.02}, {5, 10.00}, {10, 7.61}, {15, 3.15}, {20, 4.59}, {25, 3.11}, {30, 2.22}}; TableForm[salmon, TableHeadings → {None, {"Years (after 1960)", "Salmon (mil)"}}] Years (after 1960) Salmon (mil) 0 10.02 5 10. 10 7.61 15 3.15 20 4.59 25 3.11 30 2.22 Pair like (10,7.61) shows there were 7.61 million salmon in 1970. Why 1970? Because t (the number in the left column) is number of years after 1960. A pair like (10, 7.61) is called a data-point. Because it shows some data (information), and geometrically it is a point (it has two numbers). A row in our table gives us a data-point. S1. Plot the data = create a scattergram.S2. Show the graph of a line that comes close to the points in your scattegram.The line might also be known as Best fit line, Regression Line, or Least-squares regression line.S3. Find the equation of a linear function connecting S, salmon population (in millions), with t, yearssince 1960.It is OK…
