Intelligence Quotient (IQ) scores are assumed to be normally distributed in the population. The probability that a person selected at random from the general population will have an IQ between 100 and 120 is given by S. p(x) dx. Use the graph of p(x) graphed below to answer the questions which follow: au sein DO (a) Use Simpson's Rule with n = 4 to approximateſ p(x) dx. (b) The probability that a person selected from the general population will have...

#3 One of the most common ways of measuring intelligence is the IQ test. IQ scores in the US population have an average of µ = 100 and a standard deviation of σ = 15. Suppose a researcher wanted to test whether socioeconomic status (SES) has an effect on IQ scores. The researcher takes a random sample of n = 100 people, selected from a list of the 1000 richest people in the United States. a. Based on this information,...
