Using the figures in the table above, the following regression equation was obtained. Y = 0.668 + (-0.016) X1 + (0.185) X2 + (0.224) X3 + (0.118) X4 + (0.270) X5 Interpretation 1. A constant value of 0.668 indicates that if there is no independent variable (Reliability, Responsiveness, Assurance, Empathy, and Tangible), the dependent variable (customer satisfaction) is positive. 2. X1 regression coefficient = -0.016 means that if the service of dimensions X1 has decreased; the level of customer…

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…

2.5. Statistical analysis Multivariate analysis was performed using two algorithms: PCA and 2-D HCA heat map. The PCA, based on the correlation matrix, was performed using XLStat-Pro 2015 software. The 2-D HCA heat map was carried out with the ArrayTrack, and the Ward's minimum-variance method was used for runs and hydrocarbons clustering. A probability level of p=0.05 was considered as significant difference. The data obtained from the RSM on the hydrocarbon removal were subjected to the…

Reliability Table 4.5 Reliability Test Variable Cronbach’s Alpha N of Items Remark Brand Awareness 0.825 5 Reliable Brand Association 0.757 3 Reliable Perceived Quality 0.763 4 Reliable Brand Loyalty 0.890 5 Reliable After validity test, this is the result of the reliability test. The requirement to be reliable is the Cronbach’s Alpha must be more than 0.7. As seen from the table 4.5 the Cronbach’s Alpha of every variables are more than 0.7 which are remarked as reliable. To be explained, the…

The split criterion and dead criterion are listed below. GIVE FORMULA Nsplit and Nadapt are two new parameters which have their usage in controlling and adjusting the split criterion and dead criterion. S is the initial population size and S^i is the current population size. It should be taken into consideration that the population size will increase by one if a bacterium undergoes reproduction and decrease by one if a bacterium faces lethat consequences. As a result, the population size may…

Results In order to examine the differences in metaphorical language use of the experimental group and the control group at the beginning of the metaphor awareness treatment, an independent samples t-test was conducted for the data gathered from the participants’ recent writing test. The statistical analysis indicated that there was not a significant difference in the metaphorical language use of experiment group (M = 1.59; SD = .70) and control (M = 1.44; SD = 1.00); t (43) = .58, p = .56.…

The U.S. Supreme Court denied the case of Swain vs. Alabama’s appeal in 1965. Swain was a black man convicted of raping a white women in Talladega, Alabama, which sentenced him to death. The court that found him guilty consisted of an all white jury. However, the Supreme Court still denied the appeal because the jury had been selected from a panel consisting of 100 men over the age of 21 that had 8 black men on it. They decided that the difference in the proportion of the black men over 21 on…

3. Results and discussion 3.1. Effect of pH on the percent extraction values of Sn(II) by SbS-DET. The effect of pH of reacting species such as metal ions and ligands for the formation of metal complexes is known to play a significant role in their removal and extraction processes [24]. To evaluate and identify the possible contribution of pH value of metal ion on the SbS-DET process for the formation of Sn(II)–(8HQ)2 complex via complexation and removal of Sn(II) from aqueous…

Wason Selection tasks What if there are 4 cards on the table: A, K, 2 and 7. On one side of the card there is a number and on the other a letter. You have to decide which cards to turn in order to determine if the following statement is false: If a card has a vowel on one side, then it has an even number on the other side. This is called the Wason Selection task a famous reasoning puzzle (Dawson, Gilovich, Regan, 2002). The answer to this problem is cards A and 7 instead of the most commonly…
