Question details

Step by step please. 11 In the table below, P denotes average property prices and S average property sizes in six cities in 2012. Count New Y ork Madrid Rome London Paris Tokyo 10.2 7.2 9.0 11.6 10.8 17.2 6.7 5.5 5.8 7.7 7.1 a- Determine whether the data is a time series, a cross sectional data or panel data b- Dra a scatter plot with the data of the table. Intepret your graph c- Eind the correlation coefficient (P, S) and interpret your result. d- Eind a new correlation coefficient eliminating the Tokyo observation and interpret your result.In the table below, E denotes the employment growth rate and P the productivity growth rate in the manufacturing industry in six countries for the period 1980-1990. Count Austria Belgium Canada Denmark Italy 2.0 1.7 2.0 2.4 4.0 5.9 4.0 3.9 1.5 3.0 2.0 9.6 pan a- Determine whether the data is a time series, a cross sectional data or panel data b- Draw a scatter plot with the data of the table. Interpret your graph. Calaulate the correlation coefficient (E, P) and interpret your result. d- Calculate a new correlation coefficient eliminating the Japanese observation and nterpret your result.12 Let X be a random variable knowing that: E(x)-μ and Var(x) We have information about four independent observations: x1, x2, X3, X4 Let A1x x2x3 x4) being and estimator for the population mean -σ mean a-What are the expected value and variance of A in terms of μ and σ? b- Now consider a second estimator for the population mean A2 being defined as: Show that this second estimator is also an unbiased estimator for the population mean. Find its variance c- Discuss the sufficiency of both estimators. d- Based on all your previous answers, which estimator do you prefer?
