In one of the New York City parks, there has been a problem with muggings in the summer months. A random sample of 10 summer days was selected. The number of cameras in the park (x), and the number of reported muggings on that day (y) were recorded. The data was analyzed to produce the results below, y = 9.78 - 0.493x r ^ 2 = 82.5% Calculate the correlation coefficient -0.6806 0.9083 0.6806 -0.9083
