Read the following statements. Interpret the following results and give the rationale. a. Given that the limit test is valid, one replicate of Solution A gave a positive result and the other replicate is negative. Interpretation: Rationale: Disposition:

In regard to the difference margin (M), which of the following statements is NOT right? a. the difference margin should be chosen before the start of a trial  b. the difference margin is a value randomly chosen by the researchers c. the difference margin is carefully chosen with both statistical and clinical considerations  d. Non-inferiority and equivalence in efficacy between a new treatment and the standard treatment should be claimed in the presence of a well justified difference margin

Out of these associations between a potential exposure (risk factor) and an outcome (health condition or disease), identify the one that is most likely to be causal based on the "strength" of the association. Assume that you no nothing else about the factors and/or the outcomes. Please note: the values of some associations are hypothetical/imaginary, the associations are plausible   a. A number of chemicals in tobacco products have been shown to induce cancers in laboratory settings   b. Men employed in occupations requiring them to sweep chimneys with tars and/or mineral oils have been shown to have 200 times risk of dying from scrotal cancer compared with men not engaged in such occupations.   c. Those who regularly engage in moderate to high intensity physical activity are half as likely to suffer a premature cardiac event compared with those who do not exercise at all.   d. Adults who frequently experience inadequate and/or poor quality sleep at night are…

Describe the findings of figure 2A

i found this past paper online and am using it for revision but i cannot find the mark scheme anywhere online. B2 Examples of intra-subject scatter plots between nystagmus intensity and BCVA with best-fit lines are shown in figure 3C for examples of individuals with grades 1 to 4 foveal hypoplasia. Slopes for the best-fit lines for each participant in which the r value were greater than 0.25 are shown in figure 3D. A positive slope predicts that reducing nystagmus improves BCVA. ii. What statistical parameters are generated by this approach and what do they mean?

One basic purpose of experimental design is to reduce the number of participants needed O to control variance to keep the alpha level below.05 O to observe contingencies

Read the following study, construct the appropriate 2x2 table, calculate the measure of association, state the study design, and state the interpretation of the results.A study was conducted to measure the association between radon and lung cancer in a Northeastern US city (population 15,000) which was found to have a high number of lung cancer cases. A total of 684 cases of lung cancer were found in the city. Radon testing was conducted on all the homes. Of 5,550 persons who had had homes that tested positive for radon, 478 developed lung cancer. The other 9,450 people in the city did not have radon found in their homes. 2x2 table   + - Total + A B A+B - C D C+D Total A+C B+D A+B+C+D   List the values for each cell: A, B, C, D, A+B, C+D, A+C, B+D, A+B+C+D Calculate the Risk Ratio (show your work) State your interpretation What type of study design is this?
