Question

Suppose that a random sample of 200200 ​twenty-year-old men is selected from a population and that these​ men's height and weight are recorded. a regression of weight on height yields modifyingabove weight with caret equals left parenthesis negative 102.3923 right parenthesis plus 4.0582 times height comma upper r squared equals 0.83 comma ser equals 10.5weight=(−102.3923)+4.0582×height, r2=0.83, ser=10.5​, where weight is measured in pounds and height is measured in inches. what is the​ regression's weight prediction for someone who is 7373 inches​ tall? the​ regression's weight prediction for someone who is 7373 inches tall is nothing pounds. ​(round your response to two decimal places.​)

Answer 1

The prediction is 193.86 lb.

Substituting 73 for x, we have:

-102.3923 + 4.0582*73 = 193.86
