Q2b) If rounded is 0.8151, what does that mean the pointed is?

Qdii) Your critical value says 3.891 – I think you meant 3.841?

Q3c) Is incorrect – you have already calculated the expected proportions from Q3b. Use these to calculate the rest of the Chi Square test.

Q3d) B2 2Bb b2 are all incorrect. We did some of these together in class. Go back and review the video and the preparation materials to ensure you knowhow to do these correctly. 

Q3dii) Is incorrect – you have done the same mistake with the expected frequencies. How do you calculate these? Hint: It is NOT the proportions (1:2:1). I think also your degrees are freedom are probably wrong since your critical value is incorrect. How do you calculate degrees of freedom for a 2-way Chi square test?

Q3C) Critical value is incorrect, which probably means your degrees of freedom are wrong. How do you calculate degrees of freedom for a 2-way chi square test? Same for D.
