In a certain lottery, six numbers are randomly chosen form the set {0, 1, 2, ..., 49} (without replacement). To win the lottery, a player must guess correctly all six numbers but it is not necessary to specify in which order the numbers are selected. (a) What is the probability of winning the lottery with only one ticket? (b) Suppose in a given week, 6 million lottery tickets are sold. Suppose further that each player is equally likely to choose...

6. Listed below are actual high temperatures and the high temperatures that were forecast five days earlier. Use a .05 significance level to test the claim of a zero mean difference between the actual high temperatures and the high temperatures that were forecast one day earlier. Use our 4-step procedure. This is a matched or paired samples hypothesis test. Actual high: 80 77 81 85 73 High forecast one day earlier: 78 75 81 85 76 Step 1: Ho____. Ha:...
In a certain lottery, an urn contains balls numbered 1 to 34. From this urn, 4 balls are chosen randomly, without replacement
In a certain lottery, an urn contains balls numbered 1 to 34. From this urn, 4 balls are chosen randomly, without replacement. For a $1 bet, a player chooses one set of four numbers. To win, all four numbers must match those chosen from the urn. The order in which the balls are selected does not matter. What is the probability of winning this lottery with one ticket?
