A survey of working adults is described in an online article. The article states, "Workers with a college education had a significantly increased chance of getting a pay raise in the past year, with 35 percent of the group seeing an increase, compared with 18 percent of those with some college and 17 percent of those with high school diplomas or less." Suppose that the three samples (college degree, some college, high school diploma or less) were independently selected representative samples and that the sample size for each sample was 500. USE SALT (a) Use the given information and the five-step process for estimation problems (EMC) to calculate a 95% confidence interval for the difference in the proportion who received raises for those with a college degree and those with a high school diploma or less. (Use College Degree - High School Diploma or Less. Enter your answer using interval notation. Round your numerical values to four values.) om Biki Interpret the interval. Foru We are 95% confident that the true difference in the proportion of working adults with college degrees who saw a pay raise and the same proportion for those with a high school diploma or less falls within this interval. The bounds of the interval suggest the proportion was higher for those with a college degree (b) Use the given information and the five-step process for estimation problems (EMC) to calculate a 95% confidence interval for the difference in the proportion who received raises for those with some college and those with a high school diploma or less. (Use Some College High School Diploma or Less. Enter your answer using interval notation. Round your numerical values to four values.) Projec Scre Interpret the interval. 023-0.. We are 95% confident that the true difference in the proportion of working adults with some college education who saw a pay raise and the same proportion for those this interval. The bounds of the interval suggest the proportion was higher for those with some college education X. with a high school diploma or less falls within
