A random sample of 16 persons was used in a study of the effectiveness of a new drug used in the treatment of poison ivy. Each person had a small portion of one arm exposed to poison ivy and allowed a rash to occur. The new drug was then applied to the infected area twice daily until the rash disappeared. The results are shown below= 2.4 daysS = 1.4 daysa) Can we conclude that the true mean is less than...

You work for a pharmaceutical company that is testing a new cholesterol drug. The proportion of patients on the previous drug who had a positive treatment was 0.375. You want to see if the new drug is more effective than the previous drug. You conduct a sample of 113 patients on the new drug and find that 76 have had a positive treatment effect. The 95% confidence interval is ( 0.586 , 0.7591 ). What is the best conclusion you...

Part A: Suppose you work for a pharmaceutical company that is testing a new drug to treat ulcerative colitis. You conduct a random sample of 34 patients on the new drug and 14 of them indicated a decrease in symptoms since starting the drug regimen. You construct a 90% confidence interval for this proportion to be ( 0.2733 , 0.5502 ). What is the correct interpretation of this confidence interval? 1) We are certain that 90% of patients will be...

Problem #3: A sample of 128 hypertensive people were given an anti hypertensive drug and the drug was found to be effective in 52 of those people. (By effective, we mean that their diastolic blood pressure is lowered by at least 10 mm Hg as judged from a repeat measurement taken 1 month after taking the drug.) (a) Find a 94% confidence interval for the true proportion of the sampled population for which the drug is effective (b) Using the...

A large study showed that aspirin reduced the rate of first heart attacks. A pharmaceutical company thinks that they have a drug that will be more effective than aspirin, and plans to do a randomized clinical trial to test the new drug. They determine the following null and alternative hypotheses: Example 2: a) Ho: the new drug is not more effective than aspirin HA: the new drug is more effective than aspirin hey conduct the trial. The group that used...

7. A study was conducted to investigate the effectiveness of a new drug for treating Stage 4 AIDS patients. A group of AIDS patients was randomly divided into two groups. One group received the new drug; the other group received a placebo. The difference in mean subsequent survival (those with drugs - those without drugs) was found to be 1.04 years and a 95% confidence interval was found to be 1.04 ± 2.37 years. Based upon this information: Select one...

Citizen registration and voting varies by age and gender.
Citizen registration and voting varies by age and gender. The following data is based on registration and voting results from the Current Population Survey following the 2012 election. A survey was conducted of adults eligible to vote. The respondents were asked in they registered to vote. The data below are based on a total sample of 760. We will focus on the proportion registered to vote for ages 18 to 24 compared with those 25 to 34. The expectation is...
