Bayes Rule
Law of Conditional Probability: The conditional probability of A occurring given that B has
occurred is :
P(a/B)= P(A and B)
P(B)
Assumption A= Rain Tomorrow
Research
B= Weather Forecast (Rain tomorrow)
Find P(A/B)

8.1 Estimating the Population mean
A sample MEAN (x bar) is given and Population Standard deviation is given
Build a confidence interval where (alpha) = 100%-Confidence%
Calculate z as 0.5000- (alpha) equal the area the z yields
Find the confidence interv
Random Variables
Variables taking one of a number of possible values randomly -> Numerical Value
