Question

1. Create a hypothesis/claim about one or two proportions or means related to some of the data available. You must use a different parameter than what you used in the interval estimates, so if you used a proportion for the interval, this part must involve a mean or means, and vice versa. Include a brief explanation of why you or someone else might be interested in testing your claim (make it meaningful). Then state the hypothesis both in words and in symbols. Decide what significance level you’d like to use. The standard would be 0.05, but if you choose something else, explain why. Show all your work in testing your hypothesis based on the sample data. Explain your result. Did the data lead to a definite conclusion, or is more information needed? Is your result useful or meaningful? What might be something related you would want to investigate?

Answer 1

Researcher wants to investigate whether Remdesivir drug is effective in curation of COVID 19. For this he collects data on 80 patients. One group of 40 patients is treated with Remdesivir and other group of 20 patients is treated with placebo. The average time taken to discharge patient treated with Remdesivir is 11.4days with standard deviation 4.1days and that for placebo is 14.1days with standard deviation 6.2days.

Researcher claims that Remdesivir shortens the time to discharge the COVID 19 patient.
