1945 is paired with cancer rates for 1975. The cigarette consumption data is from 1945 to 1975 in 5-year increments. There is a strong positive linear association between annual cigarette consumption and lung cancer rates. The correlation is 0.81. If we use the line to make predictions of the number of lung cancer deaths per 100,000 people, which of the following is an example of extrapolation? a. Predict Y when cigarette consumption is 3,500 cigarettes per person. b. Predict Y when cigarette consumption is 3,800 cigarettes per person. c. Predict Y when cigarette consumption is 4,600 cigarettes per person.

Find the following for this data on the length of an eruption of a geyser at Yellowstone to the amount of time until the next eruption. Geyser Eruption Data Length of Eruption (in minutes) Time until next Eruption (in minutes) 3 4.54 2.53.55 2 68 89 83 62 75 9257 Step 1 Plot the data points. Be sure to: Title your graph Label each axis including units Use appropriate scales Step 2 Identify the correlation. Step 3 Sketch the linc of best fit. Step 4 Identify two points on the line. Step 6 Write an equation using slope and the y-intercept. Show all work. Step 7 Use your line and its equation to predict how long until the next eruption if the geyser only erupted for 1 minute. Show all work. Step 5 is: "find slope of line of best fit. Show all work."Please show all work!
