Two medicines, A and B, were examined to see their effects on weight increment of laborotories mouse. Two group samples, of each 50 mouse, were chosen randomly and were weighed after being treated with respective medicines. The results are as follows: Medicine A Σ x = 1,750 Σ x2 = 62,520 Σ x2 = 85,610 Medicine B Σ x = 1,980 *x is the mouse weight. Do a test at a significance level of 1%, with a hypothesis to indicate that medicine B has more effective effect on the mouse weight.
