For the purpose of this problem, assume that increases in electricity consumption tend to respond to increases in GDP (rather than the other way around).Consider the least squares regression line, y^=a+bxIf you want to use the model to predict electricity consumption, say which variable should be the predictor (X) and which the response (Y) for this problem.
An ecоnоmist is interested in studying the incоmes of consumers in а pаrticulаr region. The population standard deviation is known to be $1,000. A random sample of 50 individuals resulted in an average income of $15,000. What is the upper end point in a 99% confidence interval for the average income?[Formula: Confidence interval estimator of µ with σ known x±zσn]
