1. H 1 : The amount of time students sleep is correlated with increased Wingate Peak Power. H o : The amount of time students sleep is not correlated with increased Wingate Peak Power. 2. The level of confidence: p < 0.05. 3. Data: see attached Excel spreadsheet. 4. The statistical method used to analyze the collected data was a T-test. See attached Excel spreadsheet for results. 5. Because the calculated value from the T-test was greater than the p-value of 0.05, it can be concluded that there is not a statistically significant correlation between the amount of sleep a student gets and his score on the Wingate Power test.

    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.
