Determine the p-value. Hint: For the calculations, assume the single persons as the first sample.(1)The pooled proportion is Blank . (Round your answer to 2 decimal places.)(2)The decision rule is to reject if z is inside or outside the interval ( BLANK, BLANK)(Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)(3)The test statistic is z = (Round your answer to 2 decimal places.)(4)The p-value is BLANK(Round your answer to 4 decimal places.)The research department at the home office of New Hampshire Insurance conducts ongoingresearch on the causes of automobile accidents, the characteristics of the drivers, and so on.
