Hypothesis testing

Problem: Apparatus 1: what is the relationship between height of release and the initial velocity? Apparatus 2: What is the relationship between length of the ball catcher and the final velocity of the system? Additional question: What is the percentage error of the initial velocity calculated using momentum and kinematics? Percentage error between theoretical initial velocity and experimental initial velocity? How much energy is lost? note: the initial velocity calculated using kinematics…

Imprecision The lowest coefficients of variation for precision within and between series over the whole tested concentration range were found for the LIAISON CLIA and LC-MS/MS method. Then followed the RIA. The Immulite CLIA showed the highest overall values and thus the lowest precision. A detailed list of all calculated variation coefficients is provided in Table 1 (A). Sensitivity The limit of blank (LoB), limit of detection (LoD) and limit of quantification (LoQ) were determined for all…

eading Response # 1: Submit to Moodle 1. What is the commonly understood definition of gender difference? (max 100 words) /1 The term gender is generally thought of as a socially constructed difference between male and female. It is an identity or role associated with feminine and masculine traits that are prescribed based on one’s sex. When we see femininity, we assume female, as well, we see masculinity and we assume male. Gender is relational based and is defined by how we speak to and…

Question How does changing the size of the airplane affect how far the airplane goes. Hypothesis If we change the size of the airplane then the paper airplane will go further. Materials Paper, graph paper, meter stick, a pencil, Procedure: 1.I will build two identical paper airplanes. One will be my control airplane that is smaller and the other will be my test airplane the one that is bigger. 2.I will throw my control plane 10 times and I will use a meter stick to measure the distance of…

there is 3 independent conditions/hypothesis, which consists of two main effects and one interaction effect (Sukal, 2013). • Null hypothesis 1: There is no statistically significant difference among individuals with dual diagnosis and the level of mental health treatment received. Alternative hypothesis 1: There is a statistically significant difference among individuals with dual diagnosis and the level of mental health treatment received. • Null hypothesis 2: There is no statistically…

The hypothesis based on the findings of Latane and Darley (1968) that as the number of participants increased, help would become less likely was somewhat supported. The results in the graph Percentage of people who helped/did not help highlighted that the bystander effect occurred as the smallest group size had the highest help rate of 100%, and the percentage of participants who helped in the group of 19 was higher than that of the group of 35, 10.5% and 2.90% respectively. However, the groups…

Utilizing the information from the table above the mean, median and standard deviation will be calculated. The mean equals the average of the sample by adding all the values of the samples and then dividing by the total number of items. The mean for the samples collected is 14.87 ounces which rounded up 14.9 ounces. The median is calculated to be 14.8 ounces. The median is calculated by averaging the data in order and finding the midway point of the data set. Last to find is to find the…

To assess the overall model fit of the measurement model, confirmatory factor analysis (CFA) was performed. The measurement properties resulted from CFA are summarized in Table 3. In this study, the chi-square statistic indicated the overall model was not fit very well (x^2 = 527.397, p < .001). However, The value of the normed chi-square static to sample size, showed that the model fit the data well with x^2/df at 2.028, which was lower than the recommended threshold of 3. In addition, the…
