A Child Psychologist Believes That the Results from a Standardized

A child psychologist believes that the results from a standardized behavior test fail to hold to the assumption of normality.She samples 250 results from the test to evaluate normality.The average value of the 250 samples is 105.25, with a standard deviation of 21.2.She finds that 30% of the scores are greater than 168.What conclusion should she draw based solely on this finding?

A) The data could be normal because we expect 30% of the readings from this data set to be greater than 168.
B) The data are most likely not normal because drastically fewer than 30% of the observations should be this high if the data set were normal.
C) The data are most likely not normal because more than 30% of the observations should be this high if the data set were normal.
D) The determination of normality cannot reliably be made from this information.
