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.
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:
Alternative hypothesis:
Where 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.

A) the more the workers are working the more the products are made. This is because if 10 workers make 52 products and 90 people make 452 then 100 people can make 502 products.
