18)Using the appropriate formula, calculatethecovariance to 3 decimals. covariance =, now convert it to a percentage:%

19) Is the covariance positive, negative or zero?.

20) Are the variables dependent on one another?(yes, no)

21)Using the appropriate formula, calculatethe correlation coefficient to 3 decimals: r =

22) Is the correlation positive, negative or zero?

23) The null hypothesis was that development time has no effect on pupal mass. More stats need to be done, but based on the data collected so far, does it appear that they will reject the null? (yes or no)
