Solve the problem.The following data represents the average percent of possible sunshine for a certain city in Indiana. 
Draw a scatter diagram of the data for one period. Find the sinusoidal function of the form 
that fits the data. Draw the sinusoidal function on the scatter diagram. Use a graphing utility to find the sinusoidal function of best fit. Draw the sinusoidal function of best fit on the scatter diagram.
What will be an ideal response?
