I would like to know the answers for these two if you could just put them in the box that would be great...

To estimate ages of tree, forest rangers use a linear model that relates tree diameter to age. The model is useful because tree diameter is much easier to measure than tree age (which requires special tools). To find the model, use the data in the table, which were collected for a certain variety of oaks. Diameter (in.) Age (years) 15 24 32 56 49 76 90 2.5 6.0 8.0 9.0 9.5 12.5 15.5 i. Create a scatter plot of the data on your calculator. Remember to use ZOOM/STAT to get a nice window ii. Find and graph a linear function that models the data. Use D for the diameter of the tree, and A for its age. Round to the nearest thousandth. A = ii. Use the model to estimate the age of an oak whose diameter is 18 in. Round to the nearest year. A- years

Solution

(1)

linear equation that models the data y = 6.45102 x - 0.152279

(2)

the age of an oak whose diameter is 18 in 115.966 =116 years
