- The rate of oxygen evolution on the geographical location of species of plants– considering group 4 values of cerata and Cabomba species, subjected to an equal wavelength of green light, the probability value is 0.1817, which is above the critical value of 0.05 at 5% significance level. Hence, we agree with the null hypothesis, and affirm that statistically; there is no significant difference in the rate of oxygen evolution process in different plant species at 5% level of precision.
