Question

the size of the left upper chamber or the heart is one measure or cardiovascular health. 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 of 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. round all answers to four decimal places

d. what measurement separates the largest 15% of heart diameters from the lower 85%? round to 2 decimal places

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
