- Define the chi-squared distribution?Watch this Khan Academy Empirical Rule video: https://www.youtube.com/watch?v=OHR126AFFBU Use the Empirical Rule. (Do not use technology. Technology will give a slightly different answer.) Draw a sketch of the normal distribution and label the mean and 1, 2, and 3 standard devitons above and below the mean with computed values. Assume that the weight of 1-year-old girls in the USA is normally distributed with Mean = 9.5 kg, Standard Deviation = 1.1 kg. (a) 68% of the data is between which 2 values? kg -- kg (b) 95% of the data is between which 2 values? kg -- kg (c) What percentage of the data is less than 8.4 kg? rse (d) What percentage of the data is between 7.3 kg and 11.7 kg? (w) What percentage of the data is more than 12.8 kg? Submit Question ere to search RCentral Limit Theorem The mean serum cholesterol level of a large population of overweight children is 220 milligrams per deciliter (mg/dl), and the standard deviation is 16.3 mg/dl. Assume the serum cholesterol level variable is normally distributed. a. If 1 child is selected, find the probability that the mean will be between 216 and 224 mg/dl. b. If a random sample of 12 overweight children is selected, find the probability that the mean will be between 216 and 224 mg/dl.
