The first opposing article does not provide significant evidence that preworkout supplementation is safe, and can therefore be interpreted as inconclusive. The authors did not provide a specific hypothesis. In this study, researchers conducted two separate trials to determine the safety and effectiveness of a PWS on healthy men and women. The first part of the trial was meant to specifically research the safety of using PWS. The second trial took a closer look at the actual impact preworkout…

surface texture, nor mass of block has that big of an impacted on the friction. The higher the percent difference is the more effect friction would have on it, with the lower percent difference says it wouldn’t affect friction. For surface area testing side A against side B on smooth sliding for percent difference was60.78%, over half (50%) but not by much. For weight off sandpaper the difference was only 40.00%, where on sandpaper it went up to 45.71%. Still less than half meaning it does not…

The first part of the experiment required one to trace the light rays going through a converging and diverging lenses. By setting up the light source towards the end of the paper and placing the lenses about 5 cm in front of the light the focal distances were found to be 14 cm for the converging lens and -5.5cm for the diverging lens. These focal distances theoretically make since because the converging lens causes the light rays to combine in front of the lens making it positive and the…

Background & Objectives: Arthropods have neurogenic hearts, which have pacemakers as part of the nervous system found outside the heart. Vertebrates and molluscs have myogenic hearts, where the pacemaker is composed of specialized cardiac muscle within the heart. Daphnia is unique as it is a cladoceran crustacean reported to have a myogenic heart. To test this, use drugs known to change heart rate in myogenic hearts and observe if they have the same influence on Daphnia. Methods: Used a…

In order to discuss the differences between clinical and statistical significance, it is important to understand what each means separately. According to Polit & Beck, statistical significance refers to "the results from an analysis of sample data are unlikely to have been caused by chance, at a specific level of probability" (2018). On the other hand, Polit & Beck define clinical significance as “the practical importance of research results in terms of whether they have genuine, palpable…

the fact that it is the largest representation of a habitat. A t-test is a statistical analysis that compares the means of two populations, wherein the variances of the data determine whether or not the means differ significantly. From a t-test a null hypothesis can be determined. The null hypothesis for this study is the mean number of species found within the lawn and the prairie are the same, while the alternative hypothesis states that the mean number of species found within the lawn and the…

neurological and psychological abnormalities in individuals living in various sociocultural environments. The tests comprised of pictures, words, and symbols that recorded short-term memory and cognitive function on participants. The alternative hypothesis of this study states that…

1. Measure the distance from the top of the third floor balcony to the first floor using a tape measurer. It should start from the top railing of the balcony to until it touches the floor. 2. Take a meter stick and place the front of the car at zero. Turn on the car and let it run until the front reaches the end of the meter stick. Make sure to use a timer to see how long it takes the car too travel that far. Divide the change in distance it travel by the time it took to find the velocity of…

Identify your selected problem in the first line of your posting and post your research question. “Relationship between effective Discharge Planning and Psychiatric Hospital Readmission Rate” Does effective discharge planning reduce the rate of readmission to a psychiatric hospital? According to Burns and Grove (2005), a correlational study examines the relationship between two research variables within a known situation. A correlational study determines if two variables are correlated. It also…
