      I is true because the definition of the p-value is the probability . that you would see a result this extreme if the null were true. This p-value is so low that . the probability of getting a sample like this if H were true is unlikely. B. A parameter is a number that describes the population. A statistic is a number that

      CHAPTER 4 : DISCRETE PROBABILITY DISTRIBUTIONS. Probability distributions can be represented by tables or by formulas. In DISCRETE probability distributions the variable can be only specified selected numerical values (such as {10, 14, 18, 21}, or {-5, -2.5, 0, 1.5, 6} or {0, 1, 2, . . . , n} or {all positive whole numbers}.

    • Probability: Definition

      The probability of an event is between 0 and 1. A probability of 1 is equivalent to 100% certainty. Probabilities can be expressed at fractions, decimals, or percents. 0 ≤ pr(A) ≤ 1. 2. The sum of the probabilities of all possible outcomes is 1 or 100%. If A, B, and C are the only possible outcomes, then

      Basic definition of odds and rates: If you have 6 red balls and 4 blue balls in a bag, the odds (ratio) of picking out a red ball is 6:4 or 3:2 or 1.5. The probability (rate) of picking a red ball is 6/10 or 0.6. Probability can be expressed either as a proportion as above (i.e. 0.6) or as a percentage by multiplying by 100 (i.e. 60%). ...
