5. A study of seat belt use involved children who were hospitalized after motor vehicle crashes. For a group of 128 children who were wearing seat belts, the number of days in intensive care units (ICU) has a mean of 0.83 and a standard deviation of 1.77. For a group of 350 children who were not wearing seat belts, the number of days spent in ICUs has a mean of 1.39 and a standard deviation of 2.06 (based on data from some recorded research findings) Use a 0.01 significance level to test the claim that children wearing seat belts have a lower mean length of time in an ICU than the mean for children not wearing seat belts.
