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 $\left( { } ^ { \circ } \mathrm { F } = 32 + ( 9 / 5 ) ^ { \circ } \mathrm { C } \right)$ 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 $9 / 5$

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

A) increased by a factor $9 / 5$
B) increased by a factor $5 / 9$
C) unaltered
D) decreased by a factor $9 / 5$

Quizplus · Accepted Answer

Changing the temperature scale from Celsius to Fahrenheit using the given formula does not change the relationship between OCR and temperature. Therefore, the correlation coefficient would be unaltered.

A Study on the Oxygen Consumption Rate (OCR) of Sea (∘F=32+(9/5)∘C)\left( { } ^ { \circ } \mathrm { F } = 32 + ( 9 / 5 ) ^ { \circ } \mathrm { C } \right)(∘F=32+(9/5)∘C)
