a) The Null: The two timings of drug treatment are equally effective.
b) P1=P2
c) Chi Squared test yields 4.48
d) Since Chi Squared test statistic = 4.48, the P-Value is between .02 and .05. Since a=.05, we can reject the null hypothesis.
e) We have enough evidence to reasonably determine that simultaneous drug treatment is superior to sequential drug treatment.
