Crickets make a chirping noise by sliding their wings rapidly over each other. The number seem to increase with temperature. The following observed data list the temperature (in F the number of chirps per second for the striped ground cricket.

Compute sample mean and sample standard deviation for both Temperature and Chirp 2. Draw a scatter diagram treating temperature as the explanatory variable and chirps as variable. 3. Compute the linear correlation coefficient, r. 4. Based on the scatter diagram and correlation coefficient, comment on the type of relat to exist between the two variables. the least-squares regression line
