To find out whether a new drug will reduce the spread of cancer, 9 mice which have all reached an advanced state of the disease are selected. Five mice receive the treatment and four do not. The survival times, in months from the time of the time of the experiment commenced are as follows: At the 0.05 level of significance, is there an evidence to say that the new drug is effective? Assume the two distributions to be normal equal variances.
