IQ is normally distributed with a mean of 100 and a standard deviation of 15. Suppose one individual is randomly chosen. Let X = IQ of an individual. Part (a) Give the distribution of X. X ~ , Part (b) Find the probability that the person has an IQ greater than 105. Write the probability statement. P What is the probability? (Round your answer to four decimal places.) Sketch the graph. WebAssign Plot WebAssign Plot WebAssign Plot WebAssign Plot Part (c) Mensa is an organization whose members have the top 2% of all IQs. Find the minimum IQ needed to qualify for the Mensa organization. Write the probability statement. P(X > x) = What is the minimum IQ? (Round your answer to the nearest whole number.) x = Sketch the graph. WebAssign Plot WebAssign Plot WebAssign Plot WebAssign Plot Part (d) The middle 40% of IQs fall between what two values? Write the probability statement. P(x1 < X < x2) = State the two values. (Round your answers to the nearest whole number.) x1 = x2 = Sketch the graph.
