Best ResponseYou've already chosen the best response.0Can you use a ti 83 or such calculator. If so then A) could be solved by normcdf(16,1E99, 16,2). Since the format for this is normcdf (lowerbound, upperbound, mean, standard deviation)

Best ResponseYou've already chosen the best response.0The other way is where you convert each to a zscore and then use the zscore table.

Best ResponseYou've already chosen the best response.0Yes I tried that whith a similar problem where I wrote each step down and somehow I got part of the question right and the others were not close. My issue is that I do not have a solid foundation in algebra and it is difficult for me to comprehend
