Several years ago, two companies merged. One of the concerns after the merger was the increasing burden of retirement expenditures. An effort was made to encourage employees to participate in the 401(k) accounts. Nationwide, 63% of eligible workers participated in these accounts. The accompanying data table contains responses of 30 employees of the company when asked if they were currently participating in a 401(k) account. Complete parts a through d. Click the icon to view the data table. a. Determine the sample proportion of company workers who participate in 401(k) accounts. The sample proportion is. (Round to three decimal places as needed.) b. Determine the sampling error if in reality the company workers have the same proportion of participants in 401(k) accounts as does the rest of the nation. The error is (Round to three decimal places as needed.) c. Determine the probability that a sample proportion at least as large as that obtained in the sample would be obtained if the…

Psychologists have been investigating the differences between people with at least one brother or sister and those with none. In a letter to the New England Jounal of Medicine, researchers announced the results of a survey of 472 adults in Buffalo, New York. The experiment recorded whether the respondent suffered from hypertension and whether she or he had siblings. The data were summarized as shown bellow; SIBLING NO SIBLING TOTAL Suffer from hypertention 79 39 118 Do not suffer from hypertension 262 92 354 TOTAL 341 131 472 REQUIRED Do these data allow us to conclude at the 5% significance level that adults with no siblings suffer different rates of hypertension than those with siblings?
