A pharmaceutical company has developed a new drug to help people fall asleep faster. A competing drug claims that it helps people fall asleep 30 minutes faster, on average. This company wishes to test the hypothesis that their drug helps people fall asleep even faster than that: Ho: μ = 30 vs. Ha: μ > 30. Define statistical power in the context of this problem. Select one or more:
A) Power would be the probability of not making a Type II Error.
B) Power would be the probability the company decides their drug does not help people fall asleep faster (than the competitor) when in fact it does not.
C) Power would be the probability of not making a Type I Error.
D) Power would be the probability the company decides their drug does help people fall asleep faster (than the competitor) when in fact it does.
Homework Answers
The correct description of power in this scenario would be:
Power would be the probability of not making a Type II Error.
Power would be the probability the company decides their drug does help people fall asleep faster (than the competitor) when in fact it does.
Hence,
Option A and Option D are correct.

A pharmaceutical company is testing a new drug. Of the 110 people that received the drug, 61 of the people's autoimmune disease went into remission. Using the old drug, the autoimmune disease for 50% of all the people treated went into remission. When testing whether or not the new drug is more effective than the old drug at treating people's autoimmune disease (in terms of the percentage of cases going into remission), what would be the null hypothesis? Note: All...

You work for a pharmaceutical company that has developed a new
drug. The patent on the drug will last 17 years. You expect the
drug’s profit to be $4 million in its first year and this amount
will grow at a rate of 3% per year for the next 17 years. Once the
patent expires, other pharmaceutical companies will be able to
produce the same drug and competition will drive profits to zero.

A pharmaceutical company has developed a new drug to reduce cholesterol. A regulatory agency will recommend the new drug for use if there is convincing evidence that the mean reduction in cholesterol level after one month of use is more than 20 mg/dl. The company collected data by giving the new drug to a random sample of 50 people from the population of people with high cholesterol. The sample mean reduction was 24 mg/dl and the standard deviation was 15...

A team of researchers has developed a new drug to treat atopic dermatitis, also known as eczema. They want to know if this new drug produces better results than a commonly prescribed older drug. The side effects of the two drugs are equivalent. The new drug would be more expensive to produce compared to the older drug. To address their research question, they will randomly assign patients to either the new or old drug. Each patient will be examined by...

2) A pharmaceutical company is formulating a new anti-obesity drug to target potential markets based on the population Body Mass Index (BMI) In a given country, official data claims that the average population BMI is about 25 kg/m2 with a standard deviation of 7 kg/m2. The company wishes to examine the extent up to which this claim is true and hence wants to test the Hypothesis Ho: p: 25 kg/m2 against lh:...

EXTRA CREDIT 1. A pharmaceutical company has developed a new chemotherapy drug (STOP2D) which functions as an inhibitor of the enzyme Split2. This enzyme is part of a pathway that promotes cell division. Suppose that in clinical trials, some of the patients become resistant to the drug. In order to determine the mechanism of resistance, the proteome of the patients is examined and it is found that the expression of Split2 is normal; however, the...

A pharmaceutical company has created a new drug to decrease how long patients suffer from a runny nose while having a cold. It is known that without treatment, on average, people report having a runny nose for 60 hours while having a cold. A test is organised for this new drug, hoping to prove the drug indeed decreases the duration of symptoms: 154 patients use it at the first sign of a runny nose...
