Error in Week 4 Summative Quiz

Hello - In the W4 Summative quiz, Question 3, the question asks us to calculate a “90% confidence level” (I believe this means CI) and then proceeds to provide multiple choice options that are clearly not a confidence interval at all since they are a single value.

The question should be asking us to calculate the margin of error, which is what I did and got it correct – but the question as it is currently worded is incorrect.

@mubsi, when you are back, perhaps investigate this?
