How many Kleenex should the Kimberly Clark Corporation package of tissues contain Researchers determined that 52 tissues is the average number of tissues used during cold. Suppose a random sample of 100 Kleenex users yielded the following data on ti number of tissues used during a cold : mean = 61, s-18. Using the sample informatic provided, calculate the true value of the test statistics: a. t= (61-52)/ 18. b. t=(61-52)/(18/100). c. t=(61-52)/(18/100). d. t=(61-52)/(18/10).
