How many tissues should the Kimberly Clark Corporation package of Kleenex contain? Researchers determined that 60 tissues is the mean 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: X = 52, S = 22. Using the sample information provided, calculate the value of the test statistic.
A) t = (52 - 60)/22
B) t = (52 - 60)/(22/100)
C) t = (52 - 60)/(22/100²)
D) t = (52 - 60)/(22/10)

The test statistic is calculated using the formula t = (X - μ) / (S/√n), where X is the sample mean, μ is the population mean, S is the sample standard deviation, and n is the sample size. Here, t = (52 - 60) / (22/√100) = (52 - 60) / (22/10).
