In a study whether there is a difference between the average heights (in inches) of adult females born in two different countries, random samples yielded the following results: n₁ = 120 x₁ = 62.7 s₁ = 2.50 1₂150 ₂ 61.8 s₂ = 2.62 Find the P-value to test the null hypothesis that the corresponding population means are equal against the alternative hypothesis that they are not equal. Round off the z-statistic to two decimal places before finding the P-value.
