3. It was believed that implementing strict measures is key in reducing the spread of a new
virus. A random selection of 50 regions with relaxed measures and 55 regions with strict
measures were surveyed how many cases they have. It was found that among regions with
relaxed measures, the average number of cases per million is 50,000 with standard deviation
of 35,000. Among regions with strict measures, the average number of cases per million is
60,000 with standard deviation of 30,000. Using 5% level of significance, conduct a
hypothesis test to determine if strict measures is effective in reducing cases in regions with
lower standards of living.
