In a study of the risks to children of automobile accidents, 400 records were randomly selected for the ages of children who died as occupants in motor vehicles. Of these, 285 were teenagers from 15 to 19 years old (based on data from Health Canada). At the 0.03 level of significance, test the claim that more than 2/3 of the children who died in automobile accidents were teenagers from 15 to 19 years old.
Test the given claim, and draw the appropriate graph. Use the traditional method or the P-value method of testing hypotheses (or your instructor may specify which method to use with assigned exercises). Assume that all samples have been randomly selected.
