How many tissues should a package of tissuescontain? Researchers determined that 60 tissues is the mean number of tissues used during a cold. Suppose a random sample of 100 tissue users yielded the following data on the number of tissues used during acold:
X=52, S =22. Suppose the test statistic does fall in the rejection region at =0.05. Which of the following conclusion iscorrect?
A. At =0.05, there is insufficient evidence to conclude that the mean number of tissues used during a cold is not 60 tissues.
B. At =0.05, there is sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues.
C. At =0.05, there is not sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues.
D. At =0.10, there is sufficient evidence to conclude that the mean number of tissues used during a cold is not 60 tissues.
