Answer:

<h2>2a. Positive correlation</h2><h2>2b. No</h2>

Step-by-step explanation:

2a. The consumptions would likely be positively correlated since the use of one would most likely somewhat follow the use of another.

2b. The consumption of one resource would not likely be causally related with the consumption of another, because one amount of usage would not likely cause the other.

Six hundred paving stones were examined for cracks, and 15 were found to be cracked. The same 600 stones were then examined for
9966 [12]

Answer: 0.01

Step-by-step explanation:

Let the events are :

C = paving stones found to be cracked.

D = paving stones found to be discolored.

Given : Total stones : T = 600  (i)

C = 15

D=  27

C'∩D'=  564   (ii)

Since C'∩D' = (C∪D)' = T- C∪D         (iii)

From (i) , (ii)and (ii) , we have

564 = 600- C∪D

⇒ C∪D=600- 564= 36

Formula : C∩D= C+D- C∪D

Put values , we get

C∩D= 15+27-36=6

Now ,

P(C\cap D)=\dfrac{C\cap D}{T}=\dfrac{6}{600}=0.01

The probability that it is both cracked and distorted is 0.01.
