Another scale that the parents completed for their children was the Spence Social Skills Questionnaire (SSSQ-P). The researchers wrote, “A single sample z test showed the scores on the SSSQ-P for the children with AS were significantly different from the mean of the normative population, z= -17.82, p< .05" (p. 365). What does z = -17.82 indicate for this particular set of data? O A. In the distribution of scores, the mean for these 92 children with AS is 17.82 standard deviations higher than the mean of the population. O B. In the distribution of sample means, the mean for these 92 children with AS is 17.82 standard errors of the mean higher than the mean of the population. O C. In the distribution of sample means, the mean for these 92 children with AS is 17.82 standard errors of the mean lower than the mean of the population. O D. Only 17.82% of the sample has scores more extreme, on average, than those of the population.
