QuestionListed below are the numbers of cricket chips in 1 minute and the corresponding temperatures in . Construct a scatterplot, and find the value of the linear correlation coefficient r . Is there sufficient evidence to conclude that there is a linear correlation between the number of chirps in 1 minute and the temperature? Use a significance level of .
\begin{tabular}{|l|c|c|c|c|c|c|c|c|}
\hline Chirps in 1 min & 889 & 1172 & 1092 & 857 & 1207 & 1027 & 958 & 919 \\
\hline Temperature ('F) & 71 & 92.2 & 83.6 & 75.1 & 87.8 & 81.3 & 71.1 & 79.4 \\
\hline
\end{tabular}

Studdy Solution
Determine the critical value for at with degrees of freedom (where ).
Compare the calculated with the critical value to determine if there is a significant linear correlation.
The calculated value of and the conclusion about the correlation will depend on the computations above. Please perform these calculations to find the exact value of and compare it with the critical value from a correlation table.
