If the null hypothesis of an experiment is true
a. The means of each of the conditions would be essentially the same
b. The variance of each of the conditions will differ from each other
c. The means of the conditions will differ from each other
d. The variability of the groups will correspond to the variability of the population
Question 2
An experiment is conducted to investigate the effects of three different doses of a drug (low, medium, high) on reaction time. The null hypothesis is that
a. The low dose leads to faster reaction times
b. The high dose leads to faster reaction times
c. There is no difference between the reaction times associated with the three doses
d. There is a difference between the reaction times associated with the three doses
