Discrepancy in the reading item: Two sample test for proportions

Hey Guys,
There is a small issue in the aforementioned reading item. In this thread, it was mentioned that the team has decided to use the notation N(\mu, \sigma^2) to represent a normal distribution.

However, in this reading item, we have represented \hat{p_1}, \hat{p_2} and \hat{p_1} - \hat{p_2} with the notation N(\mu, \sigma). I guess it would be great if the notation can be kept consistent in this reading item as well, so that the learners don’t get confused.

P.S. - Please unlist this thread, once the issue has been rectified.


Thanks! I have fixed the notation.
