A study оf seаt belt use invоlved children whо were hospitаlized аfter motor vehicle crashes. For a group of 123 children who were wearing seat belts, the number of days in intensive care unit (ICU) has a mean of 0.83 and a standard deviation of 1.77. For a group of 290 children who were not wearing seat belts, the number of days spent in the ICU has a mean of 1.39 and a standard deviation of 3.06. Use a 0.05 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. State the claim and opposite symbolically. State the Null and alternate hypotheses symbolically. Identify the significance level. Find the test statistic and the P-value State the decision State the conclusion
