Let t represent the year, with corresponding to 2006. Phamacy Pharmacy (a) Use a graphing utility to create a scatter plot of the data for pharmacy A. Aer you want to the graph you e Graph Layers to www and edit a c Use the regression feature to find a linear model. (Round your slope and intercept to two decimal places.) P= Repeat the procedure for pharmacy B. Aer you add to the graph you can use Graph Layers to view and edits P= (b) Assuming the numbers for the given five years are representative of

Answer 1

(a) Scatter plot of the data for pharmacy A is given below,

Here red line is the regression line whose equation is,

(10, 21.3) (7, 19.6) —201 (8.20) (9, 20.6) 46, 19.1) 10 ||

P = 15.80 + 0.54x

# Scatter plot for pharmacy B is given below

Here red line is the regression line whose equation is,

(7, 20.9) (9, 21.5) (6, 20.1) (8, 21.1/10/22)

P = 17.6 + 0.44x
