Math question

8:01 I LTE CZ A mail-attachment.googleusercontent.com C ( 4 ) The grounds keeper at the Sunview Golf course wants to know if there is a positive linear relation- PAGE 3 ship between the density of seed spread on a newly landscaped fairway and the density of new grass six months later. The following data pairs represent some sample plantings made by the grounds keeper Seed density grass density (1bs/400fy (seedlings/fr?) X y 1.0 170 2.0 200 3.0 240 4.0 300 5.0 310 6.0 290 7.0- 290 2) Construct a scatter diagram. b) Determine if r is significant at a = 5%%. If r is significant at a - 5%, then do parts c, d, e C) Find r and interpret its meaning. d) Determine the regression equation, y". e) Using the regression equation, predict the grass density given that grass seed .was applied at a rate of 3.5 (Ibs/40Oft:).
