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.The slope of the regression line was found to be positive.
If one of the analysts converted the temperatures to Fahrenheit (o F = 32 + (9/5) o C) the slope of the
Regression line 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

Question

Quizplus · Accepted Answer

The slope of the regression line would increase by a factor of 9/5 because the conversion from Celsius to Fahrenheit scales the temperature values by a factor of 9/5, thus increasing the slope of the regression line by the same factor.
