How many Kleenex should the Kimberly Clark Corporation package of tissues contain? Researchers determined that 60 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:

sample mean = 52, sample std deviation = 22.

Complete the 5 step hypothesis test at significance level 0.05; make and support your decision.

Step 1: Null and alternate hypothesis (H₀ and H_A):

Step 2: Level of Significance:

Step 3: Statistics Test/Statistics to be used:

Step 4: Rejection Criteria (draw normal curve; identify rejection area; state critical t value)

Step 5: Calculate t statistic; determine p-value; make decision about H₀
