A study was designed to examine the relationship between the TIME (in days) to complete a construction project. Data were collected on 15 projects and included the following independent variables: SIZE of the contract ($1,000s); BAD DAYS, number of bad weather days; STRIKE, a dummy variable whether or not there was a strike 1= strike, 0 = no strike; SUBCONTRACT, the number of sub-contractors involved. The correlation matrix is given below. Time Size Bad Days Strike Subcontact Time 1.000 Size 0.450 1.000 Bad Days 0.695 0.566 1.000 Strike 0.877 0.538 0.666 1.000 Subcontact 0.844 0.662 0.728 0.814 1.000 What is the correlation between SIZE and SUBCONTRACT A. .877B. .844C..695D..662
