Samples Were Drawn from Three Populations $n _ { 1 } = 6 , n _ { 2 } = 8$

question 45

True/False

Samples were drawn from three populations. The sample sizes were $n _ { 1 } = 6 , n _ { 2 } = 8$ , and $n _ { 3 } = 5$ . The sample means were $\bar { x } _ { 1 } = 2.79 , \bar { x } _ { 2 } = 1.65$ , and $\bar { x } _ { 3 } = 2.13$ . The sample standard deviations were $s _ { 1 } = 0.26 , s _ { 2 } = 0.42$ , and $s _ { 3 } = 0.49$ . The grand mean is $\bar { x } = 2.136316$ . Can you conclude that two or more of the population means are different? Use the α = 0.05 level of significance.
