Two different concrete mixtures are being tested for their bond strengths. We would like to design a hypothesis test to see if concrete mixture 2 is stronger than mixture 1. The population variances of bond strengths are σ1² = 11 and 02² = 15. If the true mean difference is 1, calculate the power of the test in detecting this difference, given n₁ =100, n=50. (assume a=0.05)
