Does duct tape work better than cryotherapy for removing warts in children and young adults? Of 26 patients treated with duct tape, 22 showed complete wart remission. In comparison, 15 of the 25 patients treated with cryotherapy achieved complete wart remission. Write the null and alternate hypothesis for this test. A Ho: pd = 0 Ha: pd < 0 where d = duct tape - cryotherapy B Ho: pd = 0 Ha: pd ≠ 0 where d =duct tape - cryotherapy C Ho: pduct tape - pcryotherapy = 0 Ha: pduct tape - pcryotherapy < 0 D Ho: pduct tape - pcryotherapy = 0 Ha: pduct tape - pcryotherapy ≠ 0 E Ho: pd = 0 Ha: pd > 0 where d = duct tape - cryotherapy F Ho: pduct tape - pcryotherapy = 0 Ha: pduct tape - pcryotherapy > 0

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…

10% of all Americans suffer from sleep apnea. A researcher suspects that a lower percentage of those who live in the inner city have sleep apnea. Of the 369 people from the inner city surveyed, 22 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.01? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion  The null and alternative hypotheses would be:     Ho: ? μ p  Select an answer = < ≠ >  (please enter a decimal)    H1: ? μ p  Select an answer > ≠ < =  (Please enter a decimal) The test statistic ? z t  = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤  αα Based on this, we should Select an answer reject accept fail to reject the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly smaller than 10% at αα = 0.01, so…

20% of all college students volunteer their time. Is the percentage of college students who are volunteers smaller for students receiving financial aid? Of the 356 randomly selected students who receive financial aid, 61 of them volunteered their time. What can be concluded at the αα = 0.10 level of significance? For this study, we should use? Select an answer z-test for a population proportion? or t-test for a population mean?         The null and alternative hypotheses would be:             H0:H0:? μ or  p  Select an answer ≥ = < > ≤ ≠   _______(please enter a decimal)          H1:H1:? μ  or  p  Select an answer ≥ ≠ = < > ≤   _______ (Please enter a decimal)        2.
