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. (Round to three decimal places as needed.) OA. The critical value is 2.337. O B. The lower critical value is The upper critical value is Should the hypothesis be rejected? Reject the null hypothesis. The evidence does suggest that community college transfer students take longer to attain a bachelor's degree. d) Construct a 95% confidence interval for Hcommunity college - Hno transfer to approximate the mean additional time it takes to complete a bachelor's degree if you begin in community college. The confidence interval is the range from 0.783 to 1.077. (Round to three decimal places as needed.) e) Do the results of parts c) and d) imply that community college causes you to take extra time to earn a bachelor's degree? O No O Yes

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
