QUESTION 26 A researcher believes taking fish oil will reduce inflammation in older adults with acute carpal tunnel syndrome. He will design and run an experiment to test his hypothesis. He selects his alpha level to be .001 and use a Z test. What is the critical region cutoff/s? +/- 1.96 +/-3.30 -3.10 -2.335

Would like to know if I calculated this correctly. Please see my answers for the questions. Endothelin is a powerful vasoconstrictor peptide derived from the endothelium. The contribution of endothelin to blood-pressure regulation in patients with hypertension was as-sessed by studying the effect of an endothelin-receptor antagonist, Bosentan. In the study, 293 patients with mild to moderate hypertension were randomized to receive one of four oral doses of Bosentan (100, 500, 1000, or 2000 mg daily), a placebo, or the ACE (angiotensin-converting enzyme) inhibitor enalapril (an established antihypertensive drug) [18]. The reported mean changes in systolic blood pressure (SBP) over a 24-hour period are shown in Table 11.23.  Table 11.23 Mean change in SBP over 24 hours Group Mean Change Bosentan dose (mg) ln(dose) Placebo -0.9 1 0 100mg bosentan -2.5 100 4.61 500 mg bosentan -8.4 500 6.21 1000 mg bosentan -7.4 1000 6.91 2000 mg bosentan -10.3 2000 7.60 11.61 What test can…

BONUS: Explain (with examples if possible) the relationship between the p-value, alpha, your obtained statistic and your critical value.

Captopril is a drug designed to lower systolic blood pressure. When Subjects were tested with this drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken, with the results below.  Use the Wilcoxon signed ranks test to see if there is sufficient evidence to support the claim that captopril is effective in lowering systolic blood pressure. State the null and alternative hypothesis. The test statistic. The critical value, your decision and conclusion.   Subject 1 2 3 4 5 6 7 8 9 10 11 12 Before 200 174 198 170 179 182 193 209 185 155 169 210 After 191 170 177 167 159 151 176 183 159 145 146 177

Good Morning,  I am needing assistance making the changes the instructor requested be changed on this question. Thank you.  Scenario:Is there a relationship between one’s gender and whether one owns a dog, cat, or reptile? Use the data provided in the table below to answer the following questions. Question: Using the degrees of freedom provided by your SPSS output and an alpha value of .05, find the critical value in the appropriate table in the Appendix of your Jackson e-book. Do not round – present all three decimal places. Clearly identify the critical value from your e-book and the obtained value from your SPSS output. Based on this information, would you reject or fail to reject the null hypothesis? Does this mean there is a significant difference or no significant difference?    My Answer:  The chi-square test of significance between the gender and pets owned is shown. The findings indicate that, with a p-value of 0.177, which is higher than the alpha value, there was no…

Open question #1 (letter b):: Explain throughly please

Psych stats question #8 show full work

A researcher conducts a two-year study comparing the number of cavities in a group of 30 randomly selected young children from the community before and after the application of fluoride to test if there is a decrease in the number of cavities. This is an example of a/an: Independent-samples t test   or    Dependent-samples t test?
