A researcher is comparing the average scores of two different training programs. The claim is that μ1≠μ2 \$$mu_1$$ \neq \$$mu_2 at a $$significance level of α=0.05 \alpha = 0.05 . The populations are normally distributed and independent. Population standard deviations are σ1=10 \$$sigma_1 = 10 $$and σ2=12 \$$sigma_2 = 12 . $$Sample statistics: xˉ1=72\bar{x}_1=72, n1=250n_1=250, xˉ2=75\bar{x}_2=75, n2=200n_2=200. What is the correct conclusion?

There is sufficient evidence to support the claim that there is a significant difference between the average scores of the two training programs
