c approximate the murder rate in a state that has 14 thousan

c. approximate the murder rate in a state that has 14 thousand registered weapons.

y is about ______murders per 100,000

The data below show the number of registered automatic weapons, in thousands, and the murder rate, in murders per 100,000 for eight randomly selected states the correlation coefficient between the number of automatic weapons and the murder b, Find the equation of the regression line c. Approximately what murder rate can we anticipate in a state that has 14 thousand registered weapons 132 101 Murder rate y Do not round untul ame final answer Then round to two decimal places as needed) b Find the equation ofthe regression line, y mak b First fnd the slope, m m (Round to two deomal places as needed Now calculate he y intercept, b. ot the regression line (Round to two decimal places as needed) c. Approximate the murder rate in a state that has 14thousand registered weapons

Solution

a. The correlation coeff = 0.834

y at x = 14 = 15.178
