Use the Matlab software to solve the two problems. If you can't use Matlab please use any available software. (show computer output) High temperature Number of F 55 340 58 335 64 410 cans sold 68 70 75 80 84 460 450 610 735 780 1. A convenience store manager notices that sales of soft drinks are higher on hotter days, so he assembles the data in the table. (a) Make a scatter plot of the data. (b) Find and graph a linear regression equation that models the data. (c) Use the model to predict soft-drink sales if the temperature is 95°F. (d) Using the scatterplot, describe the association you see between the two variables (using correlation coefficient). Make sure to mention form, direction and strength. 2. Anthropologists use a linear model that relates femur length to height. The model allows an anthropologist to determine the height of an individual when only a partial skeleton (including the femur) is found. In this problem, we find the model by analyzing the data on femur length and height for the eight males given below. (a) Make a scatter plot of the data. (b) Find and graph a linear regression equation that models the data. (c) An anthropologist finds a femur of length 58 cm. How tall was the person? (d) Using the scatterplot, describe the association you see between the two variables. Make sure to mention form, direction and strength. Femur Length (cm) 50.1 48.3 45.2 44.7 44.5 42.7 39.5 38.0 Height (cm) 178.5 173.6 164.8 163.7 168.3 165.0 155.4 155.0
