4. A scientist is trying testing the efficacy of a new drug, NuDrug. He is using the following hypotheses: H0 : NuDrug is ineffective vs. Ha : NuDrug is effective.

He collects some data and obtains a P-value of 0.0026 for this test. What is the correct interpretation of the P-value?

Answer #1

The p-value approach to hypothesis testing uses the calculated probability to determine whether there is evidence to reject the null hypothesis. If p-value is greater than the significance level (alpha), then the null hypothesis is not rejected.

H0 : NuDrug is ineffective vs. Ha : NuDrug is effective.

Given p-value is 0.0026. For significance level 0.01, this p-value(0.0026) is smaller than the significance level. Hence we reject the null hypothesis i.e. we have sufficient evidence that the NuDrug is effective.

Even for significance level higher that 0.01, the result will be the same since p-value will be smaller than the significance level n each case.

Hope it helps! Request you to give a thumbs up if it does and feel free to ask any doubts in comment section.

An experiment was conducted to test the effect of a new drug on a viral infection. After the infection was induced in 100 mice, the mice were randomly split into two groups of 50. The first group, the control group, received no treatment for the infection, and the second group received the drug. After a 30-day period, the proportions of survivors, p?1 and p?2, in the two groups were found to be 0.38 and 0.66, respectively. (a) Is there sufficient...

A new disease has annihilating amphibian populations at unprecedented levels. Researchers has been trying to develop some treatment that can counteract the disease and save some of the amphibian populations. To test which of two potential solutions is more effective, they take a sample of frogs and randomly divide them into two groups. After being treated, 257 of the 400 frogs in group 1 ended up surviving exposure to the pathogen; 300 of the 482 frogs in the second group...

A pharmaceutical company is testing a new drug to increase memorization ability. It takes a sample of individuals and splits them randomly into two groups: group 1 takes the drug, group 2 takes a placebo. After the drug regimen is completed, all members of the study are given a test for memorization ability with higher scores representing a better ability to memorize. Those 30 participants on the drug had an average test score of 32.74 (SD = 4.858) while those...

A drug manufacturer claims that its new drug causes faster red-cell buildup in anemic people than the drug currently used. A team of doctors tests the drug on 6 randomly selected people and compares the results with the current buildup factor of 7.1 (this is the buildup factor for the current drug). The results of the 6 peoples are (theses are red-cell buildup factors): 6.3 7.8 8.1 8.3 8.7 9.4. Test the manufacturer’s claim by stating the null and alternative...
