- thats the data, picture for what the graph is. working =1, not working =0
- what is a two point estimator?
- there is 520 students, 189 are studying. for tutorial 21, 8 students are studying out of 19 students.
\fQuestion 4 a) James was the tutor of tutorial 21. However, he is interested in the outcome of the overall course. To help him out, you use the information for tutorial 21 to calculate two point estimates of the average grade for the whole course using two different ways. Explain if you expect the two estimates to be the same. h) Then calculate an interval estimate for the average grade using the information from tutorial 21. If you need any further information besides that given, you are free to select it as you wish as long as you shortly explain your choice. Explain the result and discuss which assumptions you made and how these could be justified.
