Claire knows the z score for her research hypothesis is –2.05, and her critical values are –1.96 and 1.96 for a p value of 0.05. What should she conclude about her hypothesis given these statistics?

Step-by-step explanation:

Hello!

The critical values are the values of the distribution that mark the bonds of the "rejection region" and the "not rejection region".

Under the Z distribution with α: 0.05, if the critical values are -1.96 and 1.96 this means that:

-1.96 < Z < 1.96 is the "region of support" of the null hypothesis and any other value of Z, either below or equal to -1.96 or above or equal to 1.96 will determine the rejection of the null hypothesis.

In this case, the obtained Z value is -2.05, this value is less than -1.96, meaning it is within the "rejection region" so Claire should reject the null hypothesis.

I hope it helps!

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

their is no graph showing
