A subject is presented with three cups, two of which contain thesame brand of cola and one of which contains a different brand. Thesubject is to identify which one of the three cups contains adifferent brand of cola than the other two. We wish to determine ifthe subject will perform better than randomly guessing over 75trials. (Use 4 decimal places for all calculations)
a) H_0 is pi =
H_a is pi >Â Â Â
b) n*pi =Â Â and n*(1-pi) =Â Â . Is the CLTvalid? (yes/no)
Suppose the subject guessed correctly 31 times.
c) Calculate the test statistic =Â Â (this answer only 2decimal places)
d) Calculate the p-value =
e) If alpha = .05, would you reject o fail to reject thenull?
