Conduct the test. Make a decision about the null hypothesis, interpret your results and calculate effect size if applicable. At ?=.05can you reasonably say that the new drug is better? D. Now assume that you learned that he doesn’t actually know the population standard deviation and he basically made it up.What should you do now? Re-do the test with the necessary adjustments and explain your conclusion.

You are a biochemist working at a major pharmaceutical company. You and your team are tasked with developing an improved common cold medication that has lower rates of side effectsthan the one that the company is currently marketing as its main over-the-counter symptom reliever. You think you found a variationof the known, proprietary molecule that is much better in terms of the side effects. Partnering with the local clinic, you find 10 volunteers to use the new drug (after necessary clinical phases)and record the number of side effects they experience over a period of two weeks. The data are:Xi: 0, 0, 2, 1, 1, 1, 0, 1, 0, 3You ask one of the interns in the team to pull the info from the database about side effects rate in the current drug. The intern tells you that the mean rate for the current drug is 1.8, with a standard deviation of .4.

C. Conduct the test. Make a decision about the null hypothesis, interpret your results and calculate effect size if applicable. At ?=.05can you reasonably say that the new drug is better?

D. Now assume that you learned that he doesn’t actually know the population standard deviation and he basically made it up.What should you do now? Re-do the test with the necessary adjustments and explain your conclusion.
