Using our basic counting principles there will be 4 j outcomes containing j wins and so P(X = 3) = 4 ×0.5 = 0.25. Similarly with 8 games there are 28 = 256 equally likely outcomes and this time P(Y = 5) = 56×0.58 = 0.2188 so the former is larger. Khordad 5, 1400 AP ...

Significance tests give us a formal process for using sample data to evaluate the likelihood of some claim about a population value. Learn how to conduct significance tests and calculate p-values to see how likely a sample result is to occur by random chance. You'll also see how we use p-values to make conclusions about hypotheses.74. A “random survey” was conducted of 3,274 people of the “microprocessor generation” (people born since 1971, the year the microprocessor was invented).
