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]

1-A regression analysis between weight (y in pounds) and height
(x in inches) resulted in the following least squares line:
?̂=120+5? This implies that if the height is increased by 1 inch,
the weight is expected to:
A. increase by 5 pounds
B. increase by 24 pounds
C. increase by 1 pound
D. decrease by 1 pound
If the coefficient of correlation is -0.60, then the coefficient
of determination is:
A. 0.36
B. -0.36
C. -0.60
D. 0.40

The PulseRates data set has pulse, height and weight for 90
patients who had an echocardiogram test in one of the clinic in
Ottawa in the month of September. (a)[2] Fit a L-S regression line
using height to predict the pulse rate (pulse rate is called the
response variable). What is the equation of the L-S regression
line? . Does it make sense to use this line? Why? (Check the
correlation coefficient)
