. upper left chamber is enlarged, the risk of heart problems is increased. The paper "Left Atrial Size Increases with Body Mass Index in Children" (International Journal of Cardiology [2009]: 1–7) described a study in which the left atrial size was measured for a large number of children age 5 to 15 years. Based on this data, the authors concluded that for healthy children, left atrial diameter was approximately normally distributed with a mean of 26.4 mm and a standard deviation of 4.2 mm. (a) Approximately what proportion of healthy children have left atrial diameters less than 24 mm? (b) Approximately what proportion of healthy children have left atrial diameters between 25 and 30 mm? (c) For healthy children, what is the value for which only about 20% have a larger left atrial diameter? [4] Suppose that the mean value of interpupillary distance (the distance between the pupils of the left and 2. right eyes) for adult males is 65 mm and that the population standard deviation is 5 mm. Suppose that a random sample of 100 adult males is to be obtained. (a) what is the probability that the sample mean distance ¯x for these 100 will be between 64 and 67 mm?
