A scientist is interested in the relationship between the number of eggs hatched per day for frogs (y) and temperature. Based on the collected data, the least-squares regression line is ý = 15.66 + 3 58x, where x is the number of degrees by which temperature exceeds 60 degrees Fahrenheit. Which of the following statements best
describes the meaning of the slope of the least squares regression line?
O For each increase of one degree Fahrenheit per day, there is an estimated increase of 15.66 hatched eggs.
O For each increase of one hatched egg, the estimated temperature per day increases by 15.66 degrees Fahrenheit
O For each increase of one degree Fahrenheit per day, there is an estimated increase of 3.58 hatched eggs
For each increase of one hatched egg, the estimated temperature per day increases by 3.58 degrees Fahrenheit
The slope has no meaning because the units of measure for x and y are not the same.
