Question 6 The height of girls follows a normal distribution with mean u = 170 cm and the variance a2 = 16 cm?, while the height of boys is normal distribution with mean u = 174 cm and the variance o2 = 9 cm2. The height of a random sample of 10 girls and a random sample of 10 boys is measured. Calculate the probability that in this sample the average height of the girls exceeds that average height of the boys. %3D
