In one of Boston's public parks, mugging in summer months has been a serious issue. A police cadet took a random sample of 10 days and compiled the data. For each day, x represents the number of police officers on duty in the park and yrepresents the number of reported muggings on that day. x 10 15 16 1 4 6 18 12 14 7 y 5 2 1 9 7 8 1 5 3 6 n=10,∑x=103,∑y=47,SSxx=286.1,SSyy=74.1,SSxy=−141.1 The least squares estimate of the slope β^1is about Group of answer choices -0.49 -0.26 1.00 0.26 0.49
