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.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

i belive those are the ones that are under 90 degreese.
