Ok, maybe I've just studied too much and forgot something simple but I can't figure out how to calculate the p-value for some reason?

My class notes say to use excel and use NORMSDIST(Z-value) which I'm inputing as 2.1948 and getting .985911 but Webassign won't accept it. Anyone know another formula instead of excel?

Thanks!

ti-83 plus...hit 2nd, vars, normalcdf. type in -99,2.1948) ... .985911, either you are doing something wrong with the z value or it wants 1 - .985911.

didn't want 1-.9859 either.... I know the z-value is right b/c webassign already counted it as right previously in part of the question earlier.

Nevermind, tried it again and it took it that time! (love webassign ). It did want the 1-.

Thanks!!!
