*Q: As mentioned in the text, there is a difference between a research hypothesis and a statistical hypothesis. In your own words, describe the difference between these two types of statements and when each is to be used in research. Then write a null and alternate hypothesis for a research problem you may be interested in addressing through statistical analysis. Lastly, comment how probability (p-values) are used in statistical analysis. Your response should be a minimum of 400 words.*

*My attempt is:*

*Research Hypothesis: The official industry definition that a research hypothesis is statement created by researchers when they speculate upon the outcome of a research or experiment. My definition would be it is the question that the researcher aims at answering. A research hypothesis is the basis of all research and forms the source for a statistical analysis of the hypothesis.. It is the question that the researcher aims at answering. It can also be presented in the form of a statement and is called the thesis statement. A research question aims at forming the core direction of the research. The research question forms the first methodological step in forming the research methodology.*

*My Research Hypothesis statement is:*

*Research Hypothesis: The use of automated cockpit technology in aircraft operations has improved pilot efficiency and safety of flight by interfacing technology with human factors.*

*The Null Statement and Alternate hypothesis is: Technology has a positive effect on aircraft safety*

*Technology has no effect on aircraft safety*

*Question 1: *

*You conducted a t-test in your 691 capstone research. You found a statistically significant difference between your groups even though your sample size was relatively small. Upon conducting a post hoc power analysis you found that your actual power was 0.65. What should you do? Is there a problem with having a power less than 0.80 when you have significant differences? *

*Question 2: *

*You conducted a t-test in your 691 capstone research. You did not find a statistically significant difference between your groups even though your sample size was relatively small. Upon conducting a post hoc power analysis you found that your actual power was 0.57. What should you do? Is there a problem with having a power less than 0.80 when you do not have significant differences?*
