Recap
When we 1st learned about normal distribution, we typically knew true population
mean and we calculate the probability of a randomly selected unity falling into that
range.
Big switch were now using sample statistics to figure out population paramet
Reminder Conditional Probability
P(B|A)=P(B given A)
Given disease, what is P(B).
