Assuming that the variance was different in each group, a t-test was used. The value of t was calculated to be 1.99 and with a degree of freedom of 32.2 (which was calculated assuming that the variance in both groups is not the same and unknown); the P value <0.025, which is statistically significant. This indicates that time taken for overall treatment in arm II is significantly less than that of arm I.
