A study suggests that 66% of Americans say that the cost of prescription drugs is unreasonably high. Suppost that you take a random sample of 100 patients from Baptist Hospital. Let p denote the proportion of patients (among the random sample of 100 patients) who say that the cost of prescription drugs are unreasonably high.

  1. Find the probability that p exceeds 0.68. (5 points)

b. Would a sample percentage of 70% contradict the reported value of 66%? Report the test statistic (z-statistic) and p-value (5 points)

A health policy economist interested in investigating the relationship between the cost of prescription drugs in Canada and the cost of prescription drugs in the United States has information from a random sample of 51 prescription drugs sold in both countries. For each of these drugs, the economist is examining two pieces of information: the average cost x (in Canadian dollars) of a one-month supply of the drug in Canada, and the average cost y (in U.S. dollars) of a...

A recent study showed an annual per person expenditure on prescription drugs in the Northeast U.S. is $838. A follow-up study showed annual expenditures in the Midwest to be $745 per person annually there. Use a population standard deviation of $300 to answer the following questions: a. Formulate hypotheses for a test to determine whether the sample data support the conclusion that the population annual expenditure for prescription drugs per person is lower in the Midwest than in the Northeast....

Could common prescription medications be contributing to depression and rising suicide rates? A study published in JAMA found that over one-third of Americans take at least one prescription drug that lists depression as a potential side effect, and users of such drugs have a higher risk of depression than those who do not take such drugs. About 200 prescription drugs can cause depression, and the list includes common medications like proton pump inhibitors used to treat acid reflux, beta-blockers used...

Question 9 (1 point) It is reported in USA Today that the average flight cost nationwide is $595.711. You have never paid close to that amount and you want to perform a hypothesis test that the true average is actually greater than $595.711. The hypotheses for this situation are as follows: Null Hypothesis: μ ≤ 595.711, Alternative Hypothesis: μ > 595.711. A random sample of 30 flights shows an average cost of $584.559 with a standard deviation of $59.3656. What...

Question 1 (1 point) Saved It is reported in USA Today that the average flight cost nationwide is $327.31. You have never paid close to that amount and you want to perform a hypothesis test that the true average is actually different from $327.31. What are the appropriate hypotheses for this test? Question 1 options: 1) HO: μ ≤ 327.31 HA: μ > 327.31 2) HO: μ ≥ 327.31 HA: μ < 327.31 3) HO: μ ≠ 327.31 HA: μ...

A recent drug survey showed an increase in the use of drugs and alcohol among local high school seniors as compared to the national percent. Suppose that a survey of 100 local seniors and 100 national seniors is conducted to see if the proportion of drug and alcohol use is higher locally than nationally. Locally, 69 seniors reported using drugs or alcohol within the past month, while 60 national seniors reported using them. Conduct a hypothesis test at the 5%...

1. An online pharmacy advertises that its average cost of a monthly prescription for Paxil is $52 with a standard deviation of $4.50. A group of smart statistics students thinks that the average cost is higher. In order to test the store’s claim against their alternative, the students will fill a random sample of 100 prescriptions. Assume that the mean from their random sample is $52.80. What is the Z-score? What percentage of samples would have a higher average cost...
