NO EXCEL PLEASE.

Shoreline Park in Mountain View, California, has kept close tables on the number of patrons using the park since its opening in January 2015. For the first six months of operation, the following figures were recorded: a. Compute the exact values of the intercept a and the slope b from the linear regressionequations (You can use Excel to compute these numbers). b. Use a and b as the initial values of slope (trend) and intercept (base level) required in Holt's method. Assume that =0.15,=0.10 for all calculations. Suppose that the actual number of visitors using the part in July was 2150 and the number in August was 2660. Use Holt's method to update the estimates of the slope and intercept based on these observations. c. What are the one-step-ahead and two-step-ahead forecasts that Holt's method gives for the number of part visitors in September and October
