Question

The table below shows all the students who were enrolled in Math class land whether or not they passed the class.

	In Person Class	Online Class / Hybrid	Total
Passed	471	75	546
Did Not Pass	271	99	370
Total	742	174	916

Using the values calculated from the table to justify your answer, are students who take statistics in person more or less likely to pass than those who take statistics online?

Answer 1

Solution:

First we will calculate Probabilities from joint probability table

P(Statistic in Person class and passed) = No. of student who take statistic in person and Passed) / Total no. Of sample = (471/916) = 0.5142

P(Who take statistic online and passed) = No. Of student who take statistic online and passed/ Total no. Of sample = (75/916) = 0.0819

So from these above Probabilities students who take statistics in person is more likely to pass than those who take statistics online.
