The calibration curves were linear for concentrations between 15-150 µg/mL. The linearity…

A0130036Y Method 1: Box Plot The question asks if Road Handling is part and parcel of Practicality, i.e. whether road handling is an essential component influencing/affecting another data group, practicality. Thus, road handling is taken to be the independent variable, x, and is ranked from the lowest to the highest score. The data is split into 5 groups, Group 1 and 5 containing the lowest-ranked and highest-ranked road handling scores, respectively. Group 1 2 3 4 5 Median 4.58 4.585 4.455…

causes the Y. On the other hand, if the independent variable X does not help to predict Y, then the coefficients on the lags of X will all be zero in the reduced form Y equation. 7. Empirical results 7.1 Optimal lag length selection tests Before testing for the relationship among the selected variables, the optimal lag length is determined. The current study uses three different information criterion procedures, Akaike information criterion (AIC), Schwarz information criterion (SBIC) and…

Study Site We conducted this study at the Scientific Station at Las Joyas (Estación Cientifica Las Joyas) (19o35’20.7”N, 104o15’52.1”W) in the Sierra de Manantlán Biosphere Reserve, Jalisco, Mexico. Elevation reaches about 2400m above sea level. The forests transition from dry-deciduous, pine-oak, and cloud, as the elevation increases. Study Species We studied a white flowered plant with green berries and un-toothed leaves (most likely Solanum schlechtendalianum) from the genus Solanum, as it…

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…

dependent variables and the various scaling variables as the independent variables. Then the p value will be evaluated in order to determine whether the correlation between the variables are significant and we can falsify the null hypothesis and accept the alternative hypothesis that there is a relationship between the body structure and jumping performances of the toads. Toad Gender Mass (g) Body size (mm) Muscle length (mm) Muscle circumference(mm) Max. Jump (mm) 1 M 19 67 20 20 250 2 M 21.5…

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…

Answer the following question: Define the term statistical hypothesis. A hypothesis that is testable on the basis of a process being observed through a set of random variables. Define the terms null hypothesis and alternative hypothesis. The term null hypothesis refers to a general statement or a default position in which there is no relationship between two measured phenomena or no difference among groups.In other words, it is a simple hypothesis that is related to a contradiction to a theory…
