Excel-how to do a cumulative binomial test
What is the probability of getting AT LEAST 79 out of 90 correct on a True or False test?
I think I need to do a cumulative binomial test for this. But I don't know how to do this in Excel.
Would it be =Binomdist(79, 90, .5, FALSE) or would it be =1-binomdist(79,90,.5, TRUE) or neither?
I know how to do this by hand but it would take awhile. Help would be appreciated. Thanks!
