Answer to Problem 1E
Explanation of Solution
Given: The table shows number minutes out of 8 hours work day.
In table shows number of minutes out of each eight- hour work day for various years.
Let t =30 represents year corresponding to 1930 .
Now plot the scatter plot and draw each regression on graph.
Using graph the equation of regression,
Linear regression,
Quadratic regression,
Cubic regression,
So, coefficient of regression constant is nearest to 1 for cubic regression. Best fit curve would be cubic.
