I need help with a few questions. Please help!

Age of Tree Height (years) (feet) FOOD - a VIA WINE 6.0 9.5 13.0 15.0 16.5 17.5 18.5 19.0 19.5 19.7 19.8 a. Use the model to predict the height of a cherry tree when it is 22 years old. How confident are you in your prediction? Round your answer to one decimal place. The model predicts that a 22 year old tree will have a height of feet. The answer seems reasonable, however, the data shows that the older the tree gets the the height increases. b. Using the table, estimate the age of a 16 -foot cherry tree. Then use the given regression model to calculate the average age of a 16 -foot tree. Round your answer for the estimate using the table to one decimal place, and your answer for the estimate using the model to two decimal places. Using the table, the average age of a 16 -foot cherry tree is about years. Using the regression model, the average age of a 16 -foot cherry tree is about years
