Determine whether the following statements are true or false. 1. If the data are mound shaped and symmetric then, approximately 68% of the observa tions are between (a a, ,u) . 2. A parameter is a numerical descriptive measure calculated for a population. 3. Let A and B be two events such that, P(A) = 0.3 and P(B) = 0.5, then P(ALJ B) +P(A n B) = 0.8. 4. Two events are mutually exclusive (or disjoint) if they cannot occur simultaneously. 5. P(A) = 1 P(A0) 6. Roll 3 fair dice. There are 6 X 6 = 36 equally likely outcomes
