Correlation and Regression Assignment Problem 1. a. Explain which variable you chose as the explanatory variable and discuss why. * The explanatory variable is the height. This is because I am assuming that as height increases‚ the weight will increase as well. So the weight is the dependent variable b. Produce a scatter plot and insert the result here. * Scatter plot c. Find the equation of the regression line‚ Write it in the form of y=a+bx‚ where a is the y-intercept

Housing market is defined as the General market of houses being purchased and sold between buyers and sellers either directly by owners or indirectly through brokers. Housing problem is basically the problem of mismatch between the supply and demand for housing and that it can be resolved or at least reduced when a more balanced situation can be achieved. The consumers and producers both face problems and challenges in the housing market. One of the major problems faced by the consumers is the

Interpret the coefficients and calculate the price elasticity of soft drink demand 3. Omit price from the regression equation and observe the bias introduced into the parameter estimate for income. 4. Now omit both price and temperature from the regression equation.

One of the main problems that affect the livability in Hong Kong is housing problem. Hong Kong has 7.3 million people living on 1‚100 sq. km of land. There were around 6‚700 people living on every square km. However‚ the ‘right to adequate housing’ and the ‘right to affordable’ are important dimensions resting on the foundation that adequate housing is a basic human need (Leckie 1992; Bengtsson 1995) and which ensures access to a safe and affordable home with freedom from forced eviction.
