In a medical mission among adult, the distribution of cholesterol readings, in mg/dl is normally distributed with a mean of 210 and a standard deviation of 12. What percentage of this distribution will have reading greater than 240? 1. Suppose there are 10. 000 test takers of the IQ test where the population mean is 100 and the population standard deviation is 16. What is the raw score that corresponds to z = - 2.44? 2. Given the data in number 1, what is the standard score that corresponds to X = 92
