1. (2 pts.) We are going to analyze estimated average prices for five artists at ten-year intervals. These artists are: Alma Tadema 1836-1913 Breughel, Peter (Younger) 1564-1638 Courbet Renoir van Gogh 1819-1877 1841-1919 1853-1890 And the estimated prices (expressed in constant $1970) are given in "Homework 3 Data" in the tab Q1 - template (a) Using Excel, draw on one diagram a line graph of price against time for each artist. (b) Calculate the simple correlation coefficient between each pair of artists. Interpret these correlation coefficients and comment on them.
