Card 21 / 25: 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: = 52, S = 22. Give the null and alternative hypotheses to determine if the number of tissues used during a cold is less than 60.
A) H0 : X ? 60 and H1 : X
B) H0 : ? ? 60 and H1 : ?
C) H0 : ? ? 60 and H1 : ? > 60.
D) H0 : X = 52 and H1 : X? 52.
