Language C++ Ask the user to enter their weight (in pounds) and their height in inches. Calculate their Body Mass Index (BMI) and tell them whether they are underweight, overweight, or at optimal weight. BMI formula: weight * 703 / (height * height) Optimal weight is a BMI from 19 to 26. Lower is underweight, higher is overweight. Prompts: Enter your weight (in pounds): [possible user input: 144] Enter your height (in inches): [posible user input: 73] Possible Outputs: Your...

The data set cherry.csv, from Hand et al. (1994), contains measurements of diameter (inches), height (feet), and timber volume (cubic feet) for a sample of 31 black cherry trees. Diameter and height of trees are easily measured, but volume is more difficult to measure. (i) Suppose that these trees are a SRS from a forest of N = 2967 trees and that the sum of the diameters for all trees in the forest is tx = 41835 inches. Use ratio...
