Researchers determined that 60 Kleenex tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: = 52 and s = 22. Suppose the test statistic does fall in the rejection region at = 0.05. Which of the following conclusions is correct?
A) At= 0.05, we do not reject
B) At= 0.05, we reject
C) At= 0.05, we accept
D) At= 0.10, we do not reject
E) none of these
Rejection Region
In hypothesis testing, the range of values for which the null hypothesis is rejected in favor of the alternative hypothesis.
Test Statistic
A test statistic is a calculated value from sample data, used in statistical hypothesis testing to determine the likelihood of a given hypothesis.
Kleenex Tissues
A brand of paper tissues commonly used for personal hygiene and cleaning purposes.
