To find: The best fit curve of the data.
Answer to Problem 2E
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
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.
Hence, the best fit curve for the given data is cubic,
