Question

In a certain course, 24% of the students withdraw before the end of the semester. An educational company offers the class a free trial of an instructional software package designed to help student involvement. During the trial semester, 755 students took the course and used the software, of which 158 ended up withdrawing. Conduct a hypothesis test to determine if this software should be used in future semesters to lower the withdrawal rate. What is the test statistic?

Answer 1

Answer:

Yes it should continue to be used.

Step-by-step explanation:

In the course without the instructional software the percentage of students that left withdrew from the class before the semester ended was 24% and with the instructional software that was designed to help student involvement the withdrawal was 20.92% so the software should be used in future semesters and continue to be modified to better that rate.

THe percentage is calculated by diving the number of students that withdrew by the total of the students that took the course and then multiplying the result by 100:

$100(\frac{158}{755} )=20.92$
