ovely Lawns, Inc., intends to use sales of lawn fertilizer to predict lawn mower sales. The store manager estimates a probable six- eek lag between fertilizer sales and mower sales. The pertinent data are: Fertilizer Number of Fertilizer Number of Sales Mowers Sold Sales Mowers Sold eriod (tons) (six-week lag) Period (tons) (six-week lag) 1. 1.6 10 8 1.3 7 1.3 9 1.7 10 3 1.8 11 10 1.2 4 2.0 12 11 1.9 11 2.2 12 12 1.4 8 1.6 9 13 1.7 10 7 1.5 8 14 1.6 Determine the correlation between the two variables. Does it appear that a relationship exists between these variables will yield pod predictions? (Do not round intermediate calculations and round your answer to 3 decimal places.) %3D , it appears that a positive v relationship exists between these variables. Obtain a linear regression line for the data. (Negative values should be indicated by a minus sign. Do not round intermediate alculations and round your answers to 3 decimal places.) = Predict expected lawn mower sales for the first week in August, given fertilizer sales six weeks earlier of 2 tons. (Round your nswer to the nearest whole number.)
