In аn experiment meаsuring the rаte оf absоrptiоn (in g/min-cm2) two independent samples were obtained from a normal distribution. For a sample of 10 clay bricks with fine glass particles added, the sample mean was 129.3 and the population variance of 329.5. For a sample of 14 clay bricks without added glass particles, the sample mean was 150.4 and the population variance of 271.4. A two-sided 95% confidence interval of the difference of the two means was constructed. Calculate the margin of error for the confidence interval.
