One classic application of correlation involves the association between the temperature and the number of times a cricket chirps in a minute. The scatterplot in Figure 7 shows the relationship for eight different pairs of temperature/chirps data. Estimate the correlation coefficient and determine whether there appears to be a correlation between the temperature and the number of times a cricket chirps in a minute.
