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 ŷ = 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? A: For each increase of one degree Fahrenheit per day, there is an estimated increase of 15.66 hatched eggs
B: For each increase of one hatched egg, the estimated temperature per day increases by 15.66 degrees Fahrenheit.
C: For each increase of one degree Fahrenheit per day, there is an estimated increase of 3.58 hatched eggs.
D: For each increase of one hatched egg, the estimated temperature per day increases by 3.58 degrees Fahrenheit
E: The slope has no meaning because the units of measure for x and y are not the same.
