(1) (a) We roll a die 80 times and get a sum of 268. Do we have evidence at the 5% level that the die is unfair (we will call it unfair if the theoretical mean isn’t 3.5)? Do we have evidence at the 5% level that it’s weighted in favor of lower numbers? (Assume the standard deviation for the die is 1.708 in any case.) (b) Same question, when the die sums to 2680 after 800 rolls.
