One aspect 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. LY D. The samples are independent. YE. The sample sizes are large (both greater than or equal to 30). c) Does the evidence suggest that community college transfer students take longer to attain a bachelor's degree?

The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soooer hooligans. These pretest thoughts are a lorm of priming. The 200 students in group 1 had a mean score of 26.1 with a standard deviation of I 4.6, while the 200 students in group 2 had a mean score of 16.7 with a standard deviation of 4.

A random sample of40 adults with children under the age of 18 results in a mean daily leisure time of 4.07 hours, with a standard deviation oi 1.73 hours. Construct and interpret a 95% condence interval {or the mean difference in leisure time between adults with no children and adults with children ([11 p2). Let \"1 represent the mean leisure hours oi adults with no children under the age of 18 and \"2 represent the mean leisure hours of adults with children under the age of 18. The 95% condence interval for (p11 - p12) is the range tron'l hours to hours. (Round to two decimal places as needed.)
