A study on the oxygen consumption rate (OCR) of sea cucumbers involved random samples of size 3 at each of the temperatures 10, 11, 12, 13, 14, and 15oC A regression model was fit in order to study
The relationship between OCR and temperature.If one of the analysts converted the temperatures to
Fahrenheit (o F = 32 +(9/5) o C ) the correlation coefficient would be
A)increased by a factor 9/5
B)increased by a factor 5/9
C)unaltered
D)decreased by a factor 9/5
