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.

Answer :

Answer:

For this case we know that they have a sample size of n =100. And we want to test if the mean number of tissues during a cold is less than 60 "That represent the alternative hypothesis" and the complement would be the null hypothesis.

Null hypothesis: [tex]\mu \geq 60[/tex]

Alternative hypothesis: [tex] \mu<60[/tex]

Where [tex]\mu[/tex] represent the mean of tissues. And for this case we need to use a test takign in count the distribution for the mean of interest.
