Question

Using N = 148, what is the Margin of Error (ME), rounded to the nearest tenth, and is the naturopathic remedy effective in increasing the life expectancy of people with this rare disease?

Answer 1

Is there other information provided? There are several parameters missing, and you didn't include what confidence level should be calculated for. Is this for a proportion or mean?
For the second part, you can either use a confidence interval from the ME and check for effectiveness, or I would just do a t test if its a mean or a 1 proportion z interval if its a proportion.


Please provide more info.
