Find the standardized test statistic to test the claim that μ1 > μ2. Assume the two samples are random and independent. Population statistics: σ1 = 45 and σ2 = 25 Sample statistics: x1 = 685, n1 = 100 and x2 = 670, n2 = 125

Answer 1

Answer #1

Test statistic = z

= ₁ - ₂ / [²₁ / n₁ + ²₂ / n₂]

= 685 - 670 / [45² / 100 + 25²/ 125]

= 2.985

Test statistic = 2.985
