Question 1) (9 points) Suppose that a middle school is using two different teaching formats for their 6th grade math classes: Iii-Person and Online. At the end of the school year the 6th grade students are given a test where their math skills are scored as Excellent, Proficient, Needs Improvement, or At-Risk. The middle school collects the following data: m-n -s- (a) What was the sample size in this study? (b) What percentage of the sample were students that took an Iii-Person class AND scored Excellent on their test? (c) What percentage of the sample were students that took an Online class OR scored Needs Improvement on their test? (d) Construct the conditional distribution based on teaching format. Extra Credit Question 3) (1.5 points) Suppose that I am making a case sensitive password by picking 3 odd digits that do NOT repeat followed by three letters where I can choose both capital and lowercase letters and repeats are allowed. So possible passwords are 139ACa or 517zbb and so on. How many possible passwords are there of this form? (e) Which teaching format had the HIGHEST rate of At Risk scores? What was that rate? (f) Use the conditional distribution to give a one or two sentence argument for why ln-Person classes seem to be the more successful teaching format. (g) Use the conditional distribution to give a one or two sentence argument for why Online classes seem to be the more successful teaching format
