Chapter 1.2, Problem 12PB
At what age did women marry? A historian wants to estimate the average age at marriage of women in New England in the early 19th century. Within her state archives she finds marriage records for the years 1800–1820, which she treats as a sample of all marriage records from the early 19th century. The average age of the women in the records is 24.1 years. Using the appropriate statistical method, she estimates that the average age of brides in early 19th-century New England was between 23.5 and 24.7.
- a. Which part of this example gives a descriptive summary of the data?
- b. Which part of this example draws an inference about a population?
- c. To what population does the inference in part b refer?
- d. The average age of the sample was 24.1 years. Is 24.1 a statistic or a parameter?

Why the correct answer is letter A?
Students in an online course are each randomly assigned to receive either standard practice exercises or adaptivepractice exercises. For the adaptive practice exercises, the next question asked is determined by whether the studentgot the previous question correct. The teacher of the course wants to determine whether there is a differencebetween the two practice exercise types by comparing the proportion of students who pass the course from eachgroup. The teacher plans to test the null hypothesis that versus the alternative hypothesis , whererepresents the proportion of students who would pass the course using standard practice exercises andrepresents the proportion of students who would pass the course using adaptive practice exercises.The teacher knows that the percent confidence interval for the difference in proportion of students passing thecourse for the two practice exercise types (standard minus adaptive) is and the percent…
Carpetland salespersons average $8,000 per week in sales. Steve Contois, the firm's vice president, proposes a compensation plan with new selling incentives. Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increases the average sales per salesperson.

- Let us suppose we have some article reported on a study of potential sources of injury to equine veterinarians conducted at a university veterinary hospital. Forces on the hand were measured for several common activities that veterinarians engage in when examining or treating horses. We will consider the forces on the hands for two tasks, lifting and using ultrasound. Assume that both sample sizes are 6, the sample mean force for lifting was 6.2 pounds with standard deviation 1.5 pounds, and the sample mean force for using ultrasound was 6.4 pounds with standard deviation 0.3 pounds. Assume that the standard deviations are known. Suppose that you wanted to detect a true difference in mean force of 0.25 pounds on the hands for these two activities.
