Unformatted text preview: A diagram of a research study. Example: hormoneinjected rats A Very Short Introduction to Probability 52 cards Probability of A: 1 st draw: 2 d draw: 1 st draw: 1 st draw: Random sampling : 1.each individual had an equal chance of being selected 2.constant probability of being selected Solution: sampling with replacement Probability and Frequency Distribution N=10, X: 1, 1, 2, 3, 3, 4, 4, 4, 5, 6 Random sample : n = 1 P(X > 4) = ? P(X < 3) = ? Probability and The Normal Distribution Probability and The Normal Distribution 68% 95% Adult heights normalshaped distribution P(X > 80)=? Probability of randomly selecting an individual who is taller than 6 feet 8 inches? Illustration Adult heights normalshaped distribution P(X > 80)=? Probability of randomly selecting an individual who is taller than 6 feet 8 inches? Illustration 2.28% P(X > 80) = P( z > +2) = 2.28% a portion of the Unit normal table (mean 0, variance 1) Example Proportion of normal distribution corresponding to zscore values greater than 1? P(Z > 1) = Probability of selecting zscore less than 1.5? P(Z < 1.5) = Proportion of scores below z = 0.5?
