Q:
# Ramona used the regression equation y = 444x - 21.29, Ramona determined that her answer was incorrectwhere x represents height and y represents shoe size, to because a man who is -17.52 inches tall does notpredict the approximate height of a man who wears amake any sense. What was Ramona's mistake?size 8.5 shoeShe substituted the 8.5 for the wrong variable.1. y = 444(8.5) - 21.29She should have added 444 and 8.5.2 y = 3.774 - 21.29The value for y should be positive.3 y=-17.52The solution of -17.52 should be the shoe size

Accepted Solution

A:

Answer:She substituted the 8.5 for the wrong variable.Step-by-step explanation:The 8.5 refer to shoes size, not height. So, replacing 8.5 for the x-variable is wrong, because x refers to height and y represents shoe size. Therefore, Ramon just substituted the 8.5 for the wrong variable. She must replace 8.5 for y-variable, because that's the right one for shoe size.
