3. In a study to test whether there is a difference between the average height of adult females born in two different countries, random samples yielded the following results:

n1 = 120, x1 = 62.7, s1 = 2.50

n2 = 150, x2= 61.8, s2 = 2.62

where the measurements are in inches. Use 0.05 level of significance to test the difference between the average heights.
