Alpha and p values explained
Interpretation of Alpha and p-Value | BPI Consulting
1) Using P-values. This α and the P-value are used to define the decision rule. To use a P-value to make a conclusion, compare the P-value with α : If P ≤ α, then reject H0. If P > α, then fail to reject H0. Note: If H0 is rejected, H1 can be concluded as true; but failing to reject H0 does not mean H0 is accepted as true. How to find P-value

Down arrow(s) Down arrows are used to indicate if the calculated p-value is trending down over time. Green calculated values Indicates that the p-value is greater than the Level of Analysis (or alpha value). Red calculated values Indicates that the p-value is less than the Level of Analysis (or alpha …

It detailed some statistics that researchers should include when reporting different inferential test results. For the first time, a recommendation to specify the a priori alpha level was made. For the first time, the difference between the alpha level and the p-value was explained, and the reporting of exact p-values …

Interpretation: the sample estimates of alpha and beta are 123.141 and -5.57 respectively. The corresponding test statistics are 89.09 and -52.10 indicating that these are too large values of t-statististics and lie on the extreme ends of t-curve. Thus we reject the null hypothesis of alpha …

Thus, the lower the p-value the more certain that we can be that there is a statistically significant difference between the observed and hypothesized mean. Most disciplines use an alpha value of 0.05; that is, if the p-value is less than 0.05 then the difference is regarded as statistically significant. if p < 0.05, reject the null hypothesis

The p-value is reported to be less than .0001 which is indeed super small. 3.Interpret the result in #2 in the context of the problem. We have strong evidence that makes us believe that the average one year return for electric utility stocks exceeds 30%. We will reject H0 and accept the alternative hypothesis. MCS-4.
