The researcher wanted to know whether there is a relationship between the number of branches a bank has & the total number of deposits (in billions of dollars) the bank receives. So, eight regional banks are selected as the sample. Then, the number of branches and the number of deposits made are given in the table below. At 0.05 level of significance, determine if there is a significant correlation between the number of branches & the number of deposits made. Bank Number of Branches Deposits (in billion $) P 209 23 353 31 19 7 Y 201 12 344 26 A 132 401 24 L 126 4
