Question 2 A person with IQ 157 is considered as very smart in a population. In this question, we will clarify this claim in terms of probability, (a) Indeed IQ is an example of a continuous random variable. Find the following information regarding IQ online. What is its probability density function? What are the expected value and standard deviation? (b) Find constants a and b such that a IQ+b is the standard normal distribution (c) Estimate P(IQ 2 157) as follows: firstly find a constant e such that P(IQ 2 157) = P(x 2 c) where X has the standard normal distribution. Then look up the later probability from a table of standard normal distribution
