Explain how to determine whether a sample correlation coefficient indicates that the population correlation coefficient is signi
NeX [460]

The population correlation coefficient is significant if the correlation is closer to 1, less significant is closer to zero, and not significant at all if the correlation coefficient is zero.

  • Correlation coefficients are used in determining the significance of a population and the strength of the relationship <u>between two variables. </u>

  • This relationship can either be strong, weak, or not exist.

  • The correlation coefficient can have values between 0 and 1 inclusive.  The population correlation coefficient is significant if the correlation is closer to 1, less significant is closer to zero, and not significant at all if the correlation coefficient is zero.

HELP PRECALC NEED IN PROOF FORM
Vinil7 [7]

Hello, please consider the following.

We know the following, right ?

(\forall a, b \in \mathbb{R}) \left( sin(a+b)=sin(a)sin(b)+cos(a)cos(b) \right)

So, here, it gives.

Asin(\omega t+\phi)=Asin(\phi){\sf \bf sin(\omega t)}+Acos(\phi){\sf \bf cos(\omega t)}\\\\=c_2{\sf \bf sin(\omega t)}+c_1{\sf \bf cos(\omega t)}\\\\\text{ *** where }c_2=Asin(\phi) \text{ and } c_1=Acos(\phi) \text{ ***}

Do not hesitate if you need further explanation.
