Five strains of the Staphylococcus aureus bacteria were grown for 24 hours either at 35 degrees Celsius or at 43 degrees Celsius. Here are the resulting bacterial counts for each condition:
$\begin{array}{c}
\begin{array}{lll}
\text{24 hours at 35 degrees Celsius}\
66\
71\
93\
102\
62
\end{array}
\begin{array}{lll}
\text{24 hours at 43 degrees Celsius}\
98 \
67 \
42 \
31 \
77
\end{array}
\end{array}$ What is the approximate value of the correlation between bacterial count at 35 degrees Celsius and bacterial count at 43 degrees Celsius?

Question

Quizplus · Accepted Answer

The correlation between bacterial count at 35 degrees Celsius and bacterial count at 43 degrees Celsius is approximately -0.92. This indicates a strong negative correlation, meaning that as the bacterial count at 35 degrees Celsius increases, the bacterial count at 43 degrees Celsius tends to decrease.
