2. Consider a Uniform Distribution U(10, 110) D. A classmate of yours claims that those answers should be the same since if [25 < x < 85] then [x < 85} so the condition on the conditional probability is satisfied. Explain why are those answers different and the faulty logic the classmate used. (And yes I've heard this argument before) E. Find the Mean and Standard Deviation of this distribution (round to the nearest thousandth) F. Find all values within 2 Standard Deviations of this Distribution from the Expected Value. Does this Distribution have any predicted outliers from this

Suppose the scores of students on an exam are normally distributed with a mean of 165 and a standard deviation of 12. Then approximately 95% of the exam scores lie between the integers and such that the mean is halfway between these two integers. Hint: Use the 68 - 95 - 99.7 rule. For your answer, list the smaller number first.

A weight-loss clinic advertised that last month its patients, on average, lost 6 lb. Assuming that average refers to the mean, which of the following claims must be true based on this information? Note: More than one statement could be true. If none of the statements is true, mark the appropriate box. Last month, the number of their clients who lost 6 lb or more was equal to the number of their clients who lost 6 lb or less. Last month at least one of their patients lost exactly 6 lb. Last month at least one of their patients lost less than 10 lb. Two months ago some of their patients lost at least 6 lb. Last month all of their patients lost 6 lb or more. None of the above statements are true. X Ś A 181 Aa ?
