Suppose you conduct an experiment and inject a drug into three mice. Their times for running a maze are 8, 10, and 15 s; the times for two control mice are 5 and 9s. (a) Compute the difference in mean times between the treatment group and the control group (b) Write out all possible permutations of these times to the two groups and (c) What proportion of the differences are as large or larger...

An experiment was conducted to test the effect of a new drug on a viral infection. The infection was induced in 100 mice, and the mice were randomly split into two groups of 50. The first group, the control group, received no treatment for the infection. The second group received the drug. The proportions of survivors, p̂1 and p̂2, in the two groups after a 30-day period, were found to be 0.40 and 0.64, respectively. Is there sufficient evidence to...
