(c) Approximately what proportion of healthy children have left atrial diameters between 25 and 30 mm? The size of the left upper chamber of the heart is one measure of cardiovascular health. When the upper left chamber is enlarged, the risk of heart problems is increased. A paper described a study inwhich the left atrial size was measured for a large number of children aged 5 to 15 years. Based on these data, the authors concluded that for healthy children, left atrial diameter was approximatelynormally distributed with a mean of 26.7 mm and a standard deviation of 4.4 mm. (Round your answers to four decimal places.)

3) A metal box is constructed, and it's planned to have dimensions of 120 cm by 50 cm by 75 cm. If errors in production could lead to a 0.6 cm error in side length, what is the potential error in calculating the area of metal necessary to construct the box?
7. Penguins huddle together to stay warm in very cold weather. Suppose that a certain type of pen- guin has a circular cross-section approximately 14 inches in diameter (so that if you looked down on the penguin from above, the shape you would see would be a circle, 14 inches in diameter). Suppose that a group of this type of penguin is huddling in a large circular cluster, about 20 feet in diameter. (All the penguins are still standing upright on the ground; they are not piled on top of each other.)
