A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period.   Single Policyholders Married Policyholders  n1=550  n2=1,000 Number making claims = 110 Number making claims = 150   a. Use a=0.05 Test to determine whether the claim rates differ between single and married male policyholders. z-value  (to 2 decimals) p-value  (to 4 decimals)   b. Provide a 95% confidence interval (to 4 decimals) for the difference between the proportions for the two populations. Enter negative answer as negative number. (  ,   )

Determine the area under the standard normal curve that lies between z=-1.50 and z=1.50. [Please write you answer as a whole  percentage]

Sketch a standard normal curve and shade the area that lies to the left of a. -1.15 ​, b. 0.6 ​, c. 0 ​, and d. 4.2 . Then determine the area under the standard normal curve that lies in the area of interest for each part. The area to the left of -1.15 is   ​(Round to four decimal places as​ needed.) The area to the left of 0.6 is   ​(Round to four decimal places as​ needed.) The area to the left of 0 is   (Round to four decimal places as needed.) The area to the left of 4.2 is (Round to four decimal places as needed.)
