The empirical rule - Study guides, Class notes & Summaries

A random sample of CO2 levels in a school has a sample mean of x¯=598.4 ppm and sample standard deviation of s=86.7 ppm. Use the Empirical Rule to determine the approximate percentage of CO2 levels that lie between 338.3 and 858.5 ppm. Round your answer to the nearest tenth. Suppose that a random sample of redwood trees has a sample mean diameter of x¯=24.1 feet, with a sample standard deviation of s=3.7 feet. Since the diameters of redwood trees are generally symmetric and bell-shaped, ...

quantitative data - Answer Quantitative data consists of data values that are numbers, representing quantities that can be counted or measured. The Empirical Rule - Answer According to The Empirical Rule, approximately 68% of the data points in a dataset will be within 1 standard deviation of the mean. 95% of all values are within 2 standard deviations of the mean. Normal distribution - Answer In a normal distribution data is symmetrical, so the mean, median, and mode are all equal. mea...
