non-smoker subgroup, because the confounder may associated with exposure. In addition, because this is an unplanned subgroup analysis, there are unequally distribution between smoker subgroup and non-smoker subgroup, and study not randomize. Two statistical issues will be cause. The subgroup analyses can increase type 1error and type 2. Type 1 error is defined as the texts detect an effect that is not existent. Type 2 error is defined as the text failing detects an effect that is…

(2016) tested the DKT2 instrument by conducting a study on two samples of diabetes patients. The reliability or internal consistency of the instrument was determined using Cronbach’s alpha while the construct validity was determined by performing hypothesis tests to confirm the relationships between test scores and related variables (Fitzgerald et al., 2016). The findings of the study showed that the DKT2 instrument is both reliable (alphas ≥ .70) and valid. In this context, the main researcher…

Introduction I. Attention Getter: Have you ever heard the name Lucky Lindy or the Lone Eagle? II. Thesis: Today I will be talking about the great American aviator Charles Lindbergh. III. Preview: Charles Augustus Lindbergh was born on February fourth 1902. Although he was born in Detroit Michigan he spent most of his childhood in Little Falls Minnesota in Washington DC. His father whose name was also Charles Lindbergh was a US congressman from 1907 until 1917. At a young age Charles Augustus…

H1: There is a significant relationship between initiating structure and job satisfaction. Referring to last Table, Hypothesis 1 is rejected because result shows that there is no significant relationship between initiating structure and job satisfaction. The Beta value for initiating structure in last Table is 0.095, indicating that initiating structure has little influence over job satisfaction. As according to Hair et al. (2006), the bigger the Beta value, the higher the influential factor by…

Total edible oil consumption (TEO) is the dependent variable, and the independent variables are Household size(HS), Household income(HI), Household education Index(HEI), Price(P),Total Awareness score on oil(TAS) and the Ratio of Total oil expenditure to Total food expenditure (R) .θ is the disturbance term, α is the intercept term and a, b, c, d, e and f are the corresponding coefficients of the independent variables. Based on the survey data obtained from 360 respondents a regression model is…

correction as an error correction ………………………………………………………… (3.16) and obtained in this process are then interpreted and used as earlier illustrated with the simplified ECM representation in (3.15). The Engle and Granger (1987) approach to testing for co-integration is to test for stationarity of the stochastic residuals generated in the second stage of the three stage ECM procedure (Gujarati and Porter , 2009; Ogundele, 2007,Ayanwale et al 2011). Equation (3.16) will be estimated using…

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…

that Hispanic pay is greater than or equal to $30,000. The team’s alternative hypothesis or (H1) is that Hispanic pay is less than $30,000. The significance level has been set at .05 or 95%. The z score of .05 is -1.645. If the z-value is less than -1.645 then the team can reject the null hypothesis and accept the alternative hypothesis. If the z-value is greater than -1.645 then the team fails to reject the null hypothesis, meaning Hispanic workers do, in fact, make more than $30,000 a…

• PSO Algorithm to generate test cases A. Initialize the population with N Particles where Program will search for optimal solution through the movement of these particles. And Set iterations counter I = 0. B. Apply Fitness function: Calculating the fitness value by calculating the percentage of this particle will share in minimizing the total processing time to find the optimal solution. C. Compare the calculated fitness value of each particle with its (lbest). If current value is better…
