Last day b4 #xstat101 final and I’m confident that some sort of interval is on the final. This is especially true about HTing since if our hypothesize value isn’t inside the interval, maybe our hypothesis is wrong and we should reject it. #NotASubtleHint #ExamTime #TheEndIsNear

It's exam season! If there are any #xstat101 students out there, I'd probably brush up on histograms and calculating cumulative percentage - a long answer question may depend on it #NotASubtleHint #ExamTime

Oh yeah, and percentiles are our friends. Remember: P(X < c) = 0.75 means we are looking for some value "c" that gives us a probability of 75%, which is also known as the 75th percentile since 75% is◀️ and 25% is▶️of "c". #NotASubtleHint #ExamTime #xstat101 #xstat231

If you are looking for a hint for your midterm 2 tomorrow, then know that the Central Limit Theorem is the (literal) answer. #NotASubtleHint #ExamTime #xStat101 #xStat231

Imma let you finish what you were doing, but if you’re in my #xstat101 class, you should probably look at your boxplot notes for your quiz this Friday

A great thing about the empirical rule is that it tells us a lot about where the data lies the likelihood of seeing it, e.g. 95% falls within 2SD, then we expect 5% outside of 2SD AND because of symmetry, we expect approx. 2.5% is 2SD above the mean #xstat231 #xstat101

Let A = {Know formula #2 for SD for quiz #2}, then P(A) = 100% #xstat101 #xstat231 #ExamTime #NotASubtleHint
