1. Let X be a continuous random variable such that when x = 10, z = 0.5. This z-score tells us that x = 10 is less than the mean of X. Select one: True False 2. If an economist wants to determine if there is evidence that the average household income in a community is different from $ 32,000, then a two-tailed hypothesis test should be used. Select one: True False 3. α (alpha) refers to the proportion of...

A random variable Y is a function of random variable X, where y=x^2 and fx(x)=(x+1)/2 from -1 to 1 and =0 elsewhere. Determine fy(y). In this problem, there are two x values for every y value, which means x=T^-1(y)= +y^0.5 and -y^0.5. Be sure you account for both of these. Ans: fy(y)=0.5y^-0.5
