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:...
