Consider the following frequency table of observation on a random variable X. Values 01 23 4 Observed Frequency 8 16 14 9 3 (a) Perform a goodness-of-fit test to determine whether X fits the discrete uniform distribution? ( a = 0.05) (10%) (b) Perform a goodness-of-fit test to determine whether X fits the Bin(4, 0.5) distribution? (α = 0.05) (10%)
