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 STRIKE and SUBCONTRACT

A. .814

B..877

C..728

D. 1.000
