Suppose a random sample of 100 Puffs users yielded the following data on the number of tissues used during a cold: x-bar = 52 ands= 22. Suppose the test statistic does not fall in the rejection region atalpha= 0.05. Which of the following conclusions is correct?
(d) Both a and c.
(b) Atalpha= 0.05, we reject H0.
(c) Atalpha= 0.05, we accept H0.
(a) Atalpha= 0.05, we do not reject H0.
