Answer to relevant QuestionsEstimate the values of any main effects found to be significant in Exercise 15.42. With reference to the notation on page 432, show that If there are n1 = 8 letters of one kind and n2 = 8 letters of another kind, for how many runs would we reject the null hypothesis of randomness at the 0.01 level of significance? Rework Exercise 16.20 with the level of significance changed to 0.01. In exercise On what statistic do we base our decision and for what values of the statistic do we reject the null hypothesis if we have a random sample of ...A driver buys gasoline either at a Texaco station, T, or at a Mobil station, M, and the following arrangement shows the order of the stations from which she bought gasoline over a certain period of time: T T T M T M T M M T ...
