Hi, I am trying to teach myself how to test hypotheses for any distribution, but am having some trouble. X=number chosen each year θ=Mean number chosen in the population H0: θ=.5 h1: θ>.5 The random sample of n=4 is 0,1,3,3 Test the Hypotheses at α≤0.05 assuming X is a binomial(5,θ/5). This is what I have so far, but I feel I am completely missing something.. Sample average (Xbar = 1.75 So, Reject H0 if P(Xbar≥1.75, given that X is binomial(5,.1)) ≤ 0.05 Then I figure out 1-P(Xbar≤1.75)=0.08146 which is greater than 0.05 so I reject the null. I know something is not right... Any help would be much appreciated. Thanks!
