Question
Transcribed Image Text:Annie is concerned over a report that "a woman over age 40 has a better chance of being killed by a terrorist than of getting married." A
study found that the likelihood of marriage for a never-previously-wed, 40-year-old university-educated American woman was 3.1%. To
demonstrate that this percentage is too small, Annie uses her resources at the Baltimore Sun to conduct a simple random sample of 424
never-previously-wed, university-educated, American women who were single at the beginning of their 40s and who are now 45. Of these
women, 19 report now being married. Does this evidence support Annie's claim, at the 0.01 level of
of getting
significance, that the chances
married for this group is greater than 3.1 % ?
Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.

- Are birthdays "evenly distributed" throughout the year, or are they more common during some parts of the year than others? Owners of a children's toy store chain asked this question. Some data collected by the chain are summarized in the table below. The data were obtained from a random sample of 180 people. The birthdate of each person was recorded, and each of these dates was placed into one of four categories: winter (December 21-March 20), spring (March 21-June 20), summer (June 21-September 20), and fall (September 21-December 20). The numbers in the first row of the table are the frequencies observed in the sample for these season categories. The numbers in the second row are the expected frequencies under the assumption that birthdays are equally likely during each season of the year. The bottom row of numbers gives the following value for each of the season categories.

- When an audit must be conducted that involves a tedious examination of a large inventory, the audit may be very costly and time consuming if each item in the inventory must be examined. In such situations, the auditor frequently obtains a random sample of items from the complete inventory and uses the results of an audit of the sampled items to check the validity of the company's financial statement. A large company’s financial statement claims an inventory that averages $600 per item. The following data are the auditor’s assessment of a random sample of 75 items from the company’s inventory. The values resulting from the audit are rounded to the nearest dollar. Estimate the mean value of an item in the inventory using a 95% confidence interval. Is there substantial evidence (a 5 .01) that the mean value of an item in the inventory is less than $600? What is the target population for the above inferences? Would normal distribution–based procedures be appropriate for answering the…arrow_forwardAnnie is concerned over a report that "a woman over age 40 has a better chance of being killed by a terrorist than of getting married."
