Here is the data on the number of dog bites seen in the emergency department (ED) each season for the past 4 years.

Season	2016	2017	2018	2019
Winter	108	100	101	110
Spring	95	96	94	87
Summer	120	117	117	120
Fall	80	79	77	75

Apply the Least Square Regression model studied in class to forecast demand for the four seasons of the upcoming year (2020).

Hint: Review the Excel spreadsheet we used in class to set up the columns and calculations.

Expert Solution

Below is the screenshot of the regression analysis performed in excel as mentioned in Hint -

From above -

Intercept = 103.075

Slope = -0.5382

Regression Equation - Number of Dog Bites (YT) = 103.075 - 0.5382T

For 2020 Winter, T = 17

For 2020 Spring, T = 18

For 2020 Summer, T = 19

For 2020 Fall, T = 20

Y17 = 103.075 - 0.5382*17 = 93.9256

Y18 = 103.075 - 0.5382*18 = 93.3874

Y19 = 103.075 - 0.5382*19 = 92.8492

Y20 = 103.075 - 0.5382*20 = 92.311
