g. The sample means does not differ significantly because the p value is higher than 0.05…
9. The researchers stated that no significant relationship could be described between Hamstring strength indices 60°/s and functional stability. Given the data in Table 5, explain why not.…
When you perform a test of hypothesis, you must always use the 4-step approach: i. S1:the “Null” and “Alternate” hypotheses, ii. S2: calculate value of the test statistic, iii. S3: the level of significance and the critical value of the statistic, iv. S4: your decision rule and the conclusion reached in not rejecting or rejecting the null hypothesis. When asked to calculate p–value, S5, relate the p-value to the level of significance in reaching your conclusion.…
Furthermore, after running a 95% confidence interval on this data, we can say that we are 95% confidence interval on this data and we are 95% certain that the avarage (mean) annual income falls at 47,210 on the higher end of the tail, which is less than 50,000. Since the p-value of .002 is less than the alpha value of .05, we can say beyond a reasonable doubt that the manager's alternative hypothesis is correct and we will reject the null hypothesis because we have sufficient evidence for rejection.…
The p-value is 0.000 and therefore less than the α=.05 and we reject the Ho because there was not enough evidence too.…
Researchers routinely choose an alpha level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower alpha level (e.g., 0.01)? What are some situations in which you might accept a higher level (e.g., 0.1)?…
Rejection criteria: Reject the null hypothesis, if the observed significance (p-value) is less than the significance level 0.05.…
The research problem that is being explored is how to prevent infections in people who use long term indwelling urinary catheters. As patients get injured or as they age; there is a growing need to have assistance with releasing urine from the bladder. A major problem with urinary catheters is that whilst they drain the bladder, they often block the urethra and the urinary mucosa becomes inflamed, and may become damaged because of the catheter (Traunter & Darouiche, 2004). Catheter associated infections are a prevailing issue because it is best practice to reduce the costs of infections, while implementing quality and safe practices.…
i. Yes, because the significance between groups is 0.021, which is less than the significant level of 0.05. Due to the significance between the groups being smaller, it is statistically significant.…
Based on the table above, since P value is zero, the null hypothesis can be rejected.…
5. Consider t = −2.50 and t = −2.54. Which t ratio has the smaller p value? Provide a rationale for your answer. What does this result mean? Answer- The t ratio of -2.54 has a smaller p value (0.007) than the t ratio of -2.50 which has a p value of (0.01). The smaller the p values the less likely the findings will be in error. This result means that the men and women were different for physical role. The men (12.6 mean) scored higher on the physical role than the women (4.7 mean).…
4. If the researchers had set the level of significance or α = 0.01, would the results of p = 0.001 still be statistically significant? Provide a rationale for your answer.…
The study states that they would like to determine if there is a relationship because prior research was inconsistent about keeping feet flat during blood pressure measurement, but there are no actual questions worded in the study. The independent variable in this study is a participants legs being crossed at the knee. The dependent variable in this study is blood pressure readings. Researchers without a hypothesis are prepared to accept any results, but one can almost always explain superficial findings, no matter what they are. “Hypotheses guard against superficiality and minimize the risk that spurious results will be misconstrued” (Polit & Beck, 2012, p.…
The p-value or "statistical significance" of a result is the probability that the observed relationship between variables in a sample occurred by pure chance. As stated in the article, this means there is a less than one-in-10,000 probability of getting these same results if no correlation existed. Another statistical concept in the study was the use of a scatterplot to represent the data. A scatterplot is a summary of a set of bivariate data (two variables), usually created before calculating the linear correlation coefficient or fitting a regression line. The use of the scatterplot in this research study was to give a better visual picture of the relationship between the two variables and aid in the interpretation of the correlation…
Study A Explain your answer. Because the lower the p value, the less likely the results are due to chance.…
