) Scores on an IQ test are normally distributed. A sample of 20 IQ scores had standard deviation s = 8. The developer of the test claims that the population standard deviation is ı = 12. Do these data provide sufficient evidence to contradict this claim? Use the Į = 0.05 level of significance. 3) A) Reject H0. The population standard deviation appears to differ from 12. B) Do not reject H0. There is insufficient evidence to conclude that the...
