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 ha):

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
