Fast way is go to 2nd data>normalcdf(lower bound, upperbound, mean, sigma) > normalcdf(90,98,95,2.5). Please correct me if I'm wrong!
thanks!!!!
Did you do this on the calculator?
When solving for the z-score wouldn't the sample size (31 days) be included in the calculation?
So is this a probability problem or statistics? How can you tell the difference? The new civil fe specs don't have probability anymore? But it does say distribution
Hi Menga, this will definitely be in the Civil fe exam. Distributions will consist of normal, binomial and t distributions.
Good one👌
