Researchers claim that 40 tissues is the average number of tissues a person uses during the course of a cold. the company who makes puffs brand tissues thinks that fewer of their tissues are needed. what are their null and alternative hypotheses? group of answer choices1. h0: μ < 40 vs. h1: μ = 402. h0: μ = 40 vs. h1: μ < 403. h0: = 40 vs. h1: < 404. h0: μ = 40 vs. h1: μ > 40

 2.  H0: μ = 40 vs. H1: μ < 40

Step-by-step explanation:

Let be the average number of tissues a person uses during the course of a cold.

Given : Researchers claim that 40 tissues is the average number of tissues a person uses during the course of a cold.

i.e.

The company who makes Puffs brand tissues thinks that fewer of their tissues are needed.

i.e.

Thus , the set of hypothesis would be :-

Thus , the correct answer is option 2. H0: μ = 40 vs. H1: μ < 40

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
