of P-value 0.0101. (a) t the value in context. (b) What would you make if = α 0.05? If = α 0.01? Justify your answer. Correct Answer (a) If the mean score on the SSHA for older students at this school is really 115, there is a 1.01% chance of finding a sample of 45 older students with a mean score of at least 125.7. (b) Reject if = 0.05; fail to reject if = 0.01 H0 H0 α α since 0.01 < 0.0101 < 0.05. For the study of Jordanian children in , the sample mean hemoglobin level was 11.3 g/dl and the sample standard deviation was 1.6 g/dl. A significance test yields a of P-value 0.0016. (a) t the value in context.
