The answers need to be based on the data in picture two. I'm confused as to how you know which should go on the x and y. I would also like help figuring out part b (which test is best and why?). Thank you!
The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. x 11.8 8.2 6.8 3.5 2.8 2.8 2.3 0.5 y 13.9 10.8 10.1 7.2 6.5 6.5 6.3 4.8 x = thousands of automatic weapons y = murders per 100,000 residents This data can be modeled by the equation y = 0.81x + 4.35. Use this equation to answer the following; Special Note: I suggest you verify this equation by performing linear regression on your calculator. A) How many murders per 100,000 residents can be expected in a state with 7 thousand automatic weapons? Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 7.8 thousand automatic weapons? Answer = Answer = Round to 3 decimal places.

Tammy kept track of the shoe size of expectant mothers and the weights of their newborns. She recorded her data in the following scatterplot. 10 Baby Weight vs. Shoe Size y 13 12 11 10 5 6 7 8 9 10 1112 13 Mother's Shoe Size Which statement best describes the relationship shown in the scatterplot? There is no relationship between a mother's shoe size and the weight of her newborn. O G The weights of newborns were constant, but the shoe sizes of the mothers varied. OH The greater the shoe size of the mother, the lesser the weight of her newborn. The greater the shoe size of the mother, the greater the weight of her newborn. 1 2 3 8. 69 10 前Rev Baby's Weight (lb)
The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent (x) variable. Then find the best predicted weight of a bear with a chest size of 63 inches. Is the result close to the actual weight of 522 pounds? Use a significance level of 0.05.
