Statistical hypothesis testing

accurate trial. 6. Explain how the intervention(s) in the treatment arm differed from how participants in the control arm were treated. In other words, what is the trial testing? Participants in the treatment arm were given 12.5 milligram Zinc Sulfate, whereas the participants in the control arm were given a placebo. The trial is testing whether Zinc Sulfate is beneficial to children who have Malaria or not. 7. Was the trial single- or double-blinded or neither? Report evidence of assignment…

treatment assignment within program A is 1.55. Approximately 1.55 people per year (155 people every 100 years) will relapse if in the short treatment of program A. The P-value for this estimate is <0.0001. This provides strong evidence against the null hypothesis, that there is no difference between the two models. Therefore, it is likely that model 3 is better than model 2. Since these statistics indicate that the more complex model of model 3 is going to provide better results than the…

Proficiency was measured on a Likert scale from (1-7), and comprehensibility was comprised of five 7-point bipolar scale. 7. Describe the statistical tests that the researcher(s) used to analyze the data he/she/they collected. Identify which test was used for which question/hypothesis. Ignore procedures that are not related to the question/hypothesis Statistical test that were used: a. Standardized coefficient Beta b.…

Q3. If the second clerk could be added anywhere you choose (and not necessarily to check for violations, as in Question 2), what is the maximum number of applications the process can handle? What is the new configuration? Approach: Analyzed the question, we added one more clerk in step 2 (process and record payment). Then use the formula as question 1 and 2 to calculate. Figure 3.1 Solution: When add the second clerk in step 2, then solve and record payments. We could see the above pictures, 2…

In this study, 31 physicians in the age of 26 to 56 were studied. The average age of them was 41.68 ± 7.26 years. The majority (87.1%) of them were male. Most of them (64.5%) were working in 2 shifts. Table 1 represents the frequency distribution of demographic characteristics and some context variables of respondents. According to results, all of the physicians were General Practitioner. The career years were between 1 and 20 years with the average ± SD career was 9.55 ± 5.63 years. Covered…

. From table 6.7, it is observed that the Chi-square statistic is 104.089. Since P value is less than 0.01, the null hypothesis is rejected at 1 percent level of significance. Hence, concluded that there is association between stages at diagnosed as a kidney disease and cost factors in thousands of kidney patients. Based on the row percentage, Stage diagnosed as a kidney patients upto stage III, 6.0 patients are below 50000, 54.0% are 50000-100000, 26.0% are 100000-500000, 6.0% are…

In order to successfully understand minority influence were interested in finding research that determines how those individuals or minority groups who firmly uphold their own deviant or marginal standpoint can have an impact on the belief systems and behavior patterns of other individuals. Research on minority influence is of recent origin. Most research about social influence in particular, were based and entirely focused on conformity, on the way a group affects individuals and brings about…

I make this recommendation based on the data I collected from my simulated investigation. After testing the three different patch types with varying death probabilities, the patch type that was least effected by the death probability at three different rates, is the enlargement patch type. The overall average butterfly count when the death probability…

A pervious study conducting at Yale University, found that full flagellar regeneration occurred with in 90 minutes after deflagellation (Rosnbaum, et al.,1969). Our results presented evidence that our hypothesis was not supported. The average number of cells that were motile before deflagelltion was 55.56 of Chlamydomonas. The average number of cells that were motile 50 minutes after deflagellation was 43.80 motile cells. The difference in motility was…

The value of the correlation coefficient is found to be insignificant at 5 per cent level. Secondly, the correlation between ROI and QR is 0.90 which is also found to be insignificant at 5 per cent level. It reveals that there is no correlation between the two variables. It is evident from these two ratios that the lower the company's margin of safety to the short term creditors, the greater is the profitability of the concern. Thirdly, the correlation coefficient between ROI and WCR is…
