Question

QUESTION 5: At a community college, the mathematics department has been experiment with four different delivery mechanisms for content in their intermediate courses. One method is the traditional lecture Imethod I), the second is an for content in their intermediate Algebra format in which half the class time is online and the other half is face-to-face ecture (method I), the second is a hybrid method I), the third is online method and the fourth is an emporium modes Trom which students obtain their lectures and do their work in a lab with an Instructor available for assistance method IV To assess the effectiveness of the Tour methods, students in each approach are given a final exam with the results shown next. Do the data suggest that any method has a different mean score from the others?

Answer 1

Answer page: 0 Af a community college, the mathematics department has been experimenting four different delivery mechanisms. . They are method is traditional lectwie method ill → hybrid format method in online method 1 -> emporium model. @ stesponse Variable in study. and state it is a quantitative 01 qualitative. 1. In this case, the researcher aims to determine effect of different deliver mechanism on final exam swore Bo response Variable in the study is studenti final exam scote. JE is quantitative measure because it is : expstessed numerically

page-02 factor in this study and levels does it hawe.. The factor in this study is the deliver mechanism. There are 4 levels They are method i method -5 method =) method w w © null and alternative hypotheses. The null and alternative hypothesis are Ho: There is no difference in the mean sowice $ the different deliver mechanisms (42= 4 = 42 Hu Hai Not all the mean scores one equal HA 9 alternative hypothesis ( ml, # 4, + 43 € Hy)
