Executive Summary Statement of the problem Statement of research objective Assumptions We Statement of hypotheses We broke our task into three questions. In our first question we form the following hypothesis: H0: σ 2 A 2 B 2 C : All variances of Output are the same for solar cells A, B and C. HA: σ 2 A ≠ σ 2 B ≠ σ 2 C : Not all variances of Output are the same. If we reject the null hypothesis (H 0 ), there will be statistically significant evidence of a difference among the three variances.. If we Fail to Reject the null hypothesis, we will have zero percent confidence to say that there is no difference among the three variances. We can then assume equal variances for solar cells A, B, and C.

Unformatted text preview: The second question is formed as follows: H : H A : If we reject the null hypothesis (H ), there will be statistically significant evidence of a difference in the mean output for solar cells A, B, and C. We can conclude this with 95% confidence. If we Fail to Reject the null, we will have 0% confidence that all three mean outputs are the same. Data Analysis Results and Conclusions Recommendations Appendix Part I-Terminology H – Null hypothesis H A – Alternative hypothesis α (alpha) – significance level n – sample size σ 2 – population variance S 2-- sample variance μ – population mean X-- sample mean Part II-Six-step Hypothesis Testing Question 1: Question 2:...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
