The difference in standard deviations for the two instrumental methods is significant. II. The difference in standard deviations for the two instrumental methods is not significant. III. The data come from populations with the same standard deviation. IV. The data do not come from populations with the same standard deviation. II and III O II I and IV I and III II and IV
