This is a homework question: Does the obtained value exceed the critical value, 1.96? I answered that -3.08 does not exceed the critical value and we must fail to reject the null. Am I correct or have I missed a function? Instructions: Jose is the manager of a children’s baseball league. Jose wants to know if the four new teams (teams A, B, C, and D; the sample) that were added this year differ from the whole population of children’s baseball teams across the nation in terms of the number of games they won last season. For the whole league (the population), the population mean = 10.13 games won, and the σ (population SD) = 5.12. Sample Data A-1,b-2,c-4,D-2 Z= SAMPLE MEAN- POPULATION MEAN/ SEM Z= X-U/SEM X=2.25 FROM ABOVE VALUES (1+2+4+2/4) U=10.13 SEM= 2.56 Z= 2.25-10.13/2.56 Z= -7.88/2.56 Z=-3.08

Sample Data A-1,b-2,c-4,D-2
Z= SAMPLE MEAN- POPULATION MEAN/ SEM
Z= X-U/SEM
X=2.25 FROM ABOVE VALUES (1+2+4+2/4)
U=10.13
SEM= 2.56
Z= 2.25-10.13/2.56
Z= -7.88/2.56
Z=-3.08
