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 = 400 | n2 = 900 |
| Number making claims = 76 | Number making claims = 90 |
- a. Use α = .05. Test to determine whether the claim rates differ between single and married male policyholders.
- b. Provide a 95% confidence interval for the difference between the proportions for the two populations.

- In a study of how students give directions, forty volunteers were given the task ofexplaining to another person how to reach a destination. Researchers measured thefollowing five aspects of the subjects’ direction-giving behavior:• whether a map was available or if directions were given from memory without a map,• the gender of the direction-giver,• the distances given as part of the directions,• the number of times directions such as “north” or “left” were used,• the frequency of errors in directions. Identify each of the variables in this study, and whether each is quantitative orqualitative. For each quantitative variable, state whether it is discrete or continuous. Was this an observational study or an experimental study?
