Document Summary
First find z-score: mean = 70, sd = 14% (50-70)/14 = -1. 42. Pnorm with z-score: 0. 076, set lower tail as true to observe below 50% part of tail. H0: the difference between the means of voiced and voiceless consonants is 0. H1: the difference between the means of voiced and voiceless consonants is not 0. I can conclude that the sample may have come from the same statistical population. Sample is dependent: participants contribute to both treatments of voiced and voiceless.
