Answer:
Step-by-step explanation:
For testing of significance of correlation coefficient denoted by r, we create hypotheses in three ways
They are one tailed, two tailed. One tailed can be stated as right tailed and also left tailed.
The null hypothesis would normally be as r=0
Verbally we can say this there is no association between the dependent and independent variable (linear)
Against this alternate hypothesis is created as
either r not equal to 0
or r>0 or r<0
If r not equal to 0, we say two tailed hypothesis test
If r>0 is alternate hypothesis, it is right tailed test
If r<0 is alternate hypothesis, then it is left tailed test.

Step-by-step explanation:
Answer: Second Option
Step-by-step explanation:
We are evaluating aarco lengths
The formula for the arc length is:
We want to know what is the arc length for a radius of r = 8
Then we substitute r = 8 in the equation and solve
The correct answer is the second option
