Based on the above tables, there is no difference on the correlations between four variables in using one-tailed test and two-tailed test. 2. Regression

Scatterplot and regression line:
[pic]

Conclusion:

From the first table, as the value of R square is 0.09 (i.e. R = 0.3), it means that the overall quality has positive linear relationship with expected grade (as the above scatterplot and regression line you can see), and the equation of regression is: Overall quality = 1.718 + 0.526 x Expected grade. 3. One-sample t test

Result of one-sample test:

*We set H0: μ = 20; HA: μ ≠ 20

Conclusion:

From the above table, as the p-value is smaller than 0.05 (significant level) and the test value (20) is not within the confidence interval (23.60 – 28.82), we reject H0, i.e. we have insufficient evidence to conclude that 20 is the expected value of data.

4. Mann-Whitney Test

Result of test statistics:

[pic]

H0: No birth weight difference between prenatal care in the first trimester and third trimester

HA: Having birth weight difference between prenatal care in the first trimester and third trimester

Conclusion:

From the above table, as the p-value (0.033) is smaller than 0.05, we do not reject H0, that means we have sufficient evidence to conclude that there is no birth weight difference between prenatal care in the first trimester and third trimester. 5. Wilcoxon’s Matched Pairs Signed Ranks Test

Result of test statistics:
[pic]

H0: Before = After; HA: Before ≠ After

Conclusion:

From the above table, as the p-value (0.002) is smaller than 0.05, we reject H0, so we have insufficient evidence to conclude that there is no difference between the subjects’ weight pre and post intervention.

...the city
Y= duration of residence in that city
H0 = rXY=0 i.e there is NO relationship between the 2 continuous variables X and Y
Ha ≠0, there is a relationship between the 2 continuous variables X and Y
Analyze -> correlate -> bivariate
The SPSS output indicates that rXY has a value of .936. Clearly this value of rxy seems different from zero. However the question that arises is whether this value of rxy is statistically different from zero at 95% level of confidence....

...Executive Summary
The purpose of the research being undertaken is to fill a void in the literature surrounding organisations’ attitudes towards risk. The report will focus on the recent failure of the large Swiss Bank UBS; whereby an analysis of data of attitudes towards risk before and after the scandal, will give an indication on the effects the UBS bank scandal has had on financial organisations’ attitudes towards risk. In addition, through the use of correlation coefficient and...

...can communicate to anyone and almost anywhere in the world. Because of the small size of the cell phone, students can send a text quietly and discreetly. The text can go unnoticed anywhere to get help on answering tests, homework, and other class assignment. Learning in school is to behave fair not cheating.
Therefore, schools should ban students from bringing their cell phones. However it should be done fairly. In case of an emergency some student need a call for help,...

...Human nature refers to the distinguishing characteristics, including ways of thinking, feeling and acting, that humans tend to have naturally, independently of the influence of culture. The questions of what these characteristics are, what causes them, and how fixed human nature is, are amongst the oldest and most important questions in western philosophy. These questions have particularly important implications in ethics, politics, and theology. This is partly because human nature can be...

...addressed before computing the scores on the questionnaires and before conducting any analyses. This handout describes the distinction between positively-keyed items and negatively-keyed items, it describes the logic of reverse-scoring, and it outlines SPSS steps to reverse-score negatively keyed items.
Positively-keyed items and negatively-keyed items
Positively-keyed items are items that are phrased so that an agreement with the item represents a relatively high...
