Confidence Intervals for Sample Proportions: The Easy Way

[@braedencruji3517]

The videos are great, thank you very much Andrew! I am just curious as to why you did not use our new population increase of 44% for (n) in Question C part ii when it states "The population increase of 44% (and) a change of confidence from 98-95.

Thank you for the question. Question (c) is answered in two separate parts. The first part of question (c) answers the question of a 98% confidence interval with an increase in sample size (i.e., note the smaller standard error). The second part of question (c) calculates the 95% CI with the original sample size as stated in the original question. Of course, you could calculate the 95% CI with the new sample size if you wanted. Good luck!
