Researchers determined that the number of Kleenex tissues used during a cold is normally distributed with an mean of 60 and a standard deviation of 25. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: sample mean ( /x ) = 52. But, suppose the test statistic does not fall in the rejection region at a = 0.05. Which of the following conclusions is correct?

a) At a = 0.05, we do not reject H0.

b) At a = 0.05, we reject H0.

c) At a = 0.05, we reject Ha.

d) both a and c

Please show work of answer.
