We want to determine whether the mean starting salary for females in similar entry-level, nonclinical position is different from $29,500. To make this assessment, we randomly select 10 females whose job titles and responsibilities fit our criteria, and we record their starting salaries (in $1000s). The data are: 32 27 31 27 26 26 30 22 25 36 Is the mean starting salary for females significantly different from $29,500?

A researcher with the Department of Education followed a cohort of students who graduated from high school in a certain year, monitoring the progress the students made toward completing a bachelor's degree. One aspect of his research was to determine whether students who first attended community college took longer to attain a bachelor's degree than those who immediately attended and remained at a 4-year institution. The data in the table attached below summarize the results of his study. Complete parts a) through e) below. Click here to view the sample data. Click here to view Student's t-distribution table. a) What is the response variable in this study? What is the explanatory variable? O A. The response variable is the time to graduate. The explanatory variable is the use of community college or not. Sample data O B. The response variable is the time to graduate. The explanatory variable is the number of students. O C.

A company manufacturing CDs is working on a new technology. A random sample of 646 Internet users were asked: "As you may know, some CDs are being manufactured so that you can only make one copy of the CD after you purchase it. Would you buy a CD with this technology, or would you refuse to buy it even if it was one you would normally buy?" Of these users, 59% responded that they would buy the CD. Complete parts a and b below. a) Create a 99% confidence interval for this percentage. ( 54.008 %, 63.993 %) (Round to three decimal places as needed. Use ascending order.) b) If the company wants to cut the margin of error by two thirds, how many users must they survey? The company must survey a total of (Type a whole number.) users
