The research department at the home office of New Hampshire Insurance conducts ongoing research on the causes of automobile accidents, the characteristics of the drivers, and so on. A random sample of 400 policies written on single persons revealed 120 had at least one accident in the previous three-year period. Similarly, a sample of 600 policies written on married persons revealed that 150 had been in at least one accident. At the 0.05 significance level, is there a significant difference in the proportions of single and married persons having an accident during a three-year period? Determine the p-value. Hint. For the calculations, assume the single persons as the first sample. a. State the decision rule. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) Ho is rejected if z the interval (
