I am interested in knowing how best to treat depression; I want to measure the impact of different treatments on depressive symptoms. I assign 30 individuals diagnosed with major depressive disorder into 3 separate groups: 1) no treatment 2) 10mg of a common antidepressant, and 3) an exercise regimen. The DV is the number of depressive symptoms one week after treatment. Using the following data, run a between-subjects ANOVA at alpha = 0.05 to determine whether type of drug has an effect on symptoms.

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.

HYPOTHESIS TEST # 3 . The National Veterinarian ASsociation says the average cost of pet care over the lifetime of a pet = $ 6,520 with stdev = $ 318. Jim Bowser, the statistician for the NVA, claims the average is lower so he tests a sample of 32 pet owners and finds a sample mean= $ 6,423 with stdev = $ 318. At alpha = 0.05, PROVIDE A DETAILED TEST by answering the questions below.----- DO NOT USE THE P-VALUE METHOD-USE THE TRADITIONAL METHOD-do not use a t test. THE TABLE IS OPTIONAL–FILL IN ALL ANSWERS FROM A THROUGH I BELOW
BONUS: Explain (with examples if possible) the relationship between the p-value, alpha, your obtained statistic and your critical value.
The police chief selects a sample of 50 local police officers from a population of officers with a mean physical fitness rating of 75 ± 8.0 (m ± s) on a 100-point physical endurance rating scale. He measures a sample mean physical fitness rating on this scale equal to 79. He conducts a one–independent sample z test to determine whether physical endurance increased at a .05 level of significance. Compute effect size using Cohen’s d.
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.

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…
A recent issue of the AARP Bulletin reported that the average weekly pay for a woman with a high school degree is $520 . Suppose you would like to determine if the average weekly pay for all working women is signicantly greater (at alpha = 0.05) than that for women with a high school degree. Using data on weekly pay for a sample of 50 working women, you obtain the following statistics: sample mean = $620, sample error = $150. Conduct the hypothesis test using the critical value approach and the p-value approach.Describe the conclusion of the hypothesis test and what that means in this context
