Answers:
0.45 is a moderate association
0.95 and -0.8 are both strong association
0.10 is weak association
Explanation:
This is the interpreation of the correltaion coefficient:
1) The correlaion coefficient assesses the relationship between two variables in a scatter plot.
2) If the sign of the correlation coefficient is positive means that the two variables trend to grow or decrease in the same sense. This is an uphill line or curve: if variable X grows, variable Y grows, and if variable X decreases variable Y grows.
If the sign of the correlation coefficient is negative means that the two variables go in opposite direction. This is a downhill line or curve.
3) A correlation coefficient of +1 or -1 is a perfect association. The two variables are totally associated.
4) A correlation coefficient less that +1 but greater than 0.7 is a strong association. The same with a coefficite between - 0.7 and -1.
5) A correlation coefficient arroun +0.5 or -0.5 is a moderate association.
6) A correlation coefficient of 0 is a nill association.
7) A correlation coeffiicient between 0 and 0.3 is a weak association. The same when the correlation coefficient is between -3 and 0.
Answer : Second Option is correct.
Explanation :
Since we have given in the figure ,
AE=12 units
AD=9 units
EB=4 units
DC=x units
By using the BPT theorem, which states that
"If a line is drawn parallel to one side of a triangle in distinct point , the other sides are divided in the same ratio."
So, here we have a ΔABC,
in which DE║BC as shown in the figure ,
so, by using the BPT we get,
Hence, length of DC = 3 units .
I'm going to reword your question so it's easier to answer. I'm also going to pretend no one has 3 or more accounts because it's irrelevant.
22% have no accounts (220/1000)
What is the probability that 4 or more of the 10 participants has no account?
(220/1000)*(219/999)*(218/998)*(217/997)*(10 choose 4)
