As pаrt оf а study tо evаluate differences in educatiоn quality, a standardized examination is given to individuals who are trained at two training centers. The difference between the mean examination scores is used to assess quality differences between training center A & training center B. Historical standardized examinations always resulted in an examination score standard deviation near 10 points. Thus, we will assume σ 1 =10 & σ 2 =10. Independent random samples of individuals from training centers A & B provided the following information. Center A Center B Sample size n 1 = 30 n 2 = 40 Sample mean x 1 ¯ = 82 x 2 ¯ = 78 With the above data, the researcher concludes that there is no difference in the level of education between the two centers at the 0.05 significance level. Could you calculate the P-value for this conclusion? z dsistribution table from 0.0 to 2.49.jpg z = ( x 1 - x 2 ) - D 0 σ x 1 ¯ - x 2
