Answer:
<em>The cross-correlation ,autocorrelation and its coefficient are explained.</em>
Step-by-step explanation:
Solution:
The similarity of two signals is given by the term called cross-correlation .
It is also called as sliding dot product.
The auto-correlation function of signal is defined as signal compared with respect to the time with itself or with time lag .
It is the function of serial correlation with delayed copy of itself.
And the cross correlation is the function of two independent signal with time shifts in the time which are often in advancement rather in delayed in auto-correlation.
The correlation coefficient of signal is ,
consider two signal x(n) and y(n)
there coefficient is given by the
,equation {}/.
The time and sampling must be matched for the two signals .
if the above equation ;
if the signals are identical then the roots being same gives the extreme value of "1"
if the signals are out of phase to each other then the value for equation will be "-1".
Step-by-step explanation:
the number divisible by 3 is the digit add together can divisible by 3.
778 is 7+7+8=22 (can't divisible by 3)
339 is 3+3+9=15 (can)
483 is 4+8+3=15 (can)
2747 is 2+7+4+7=20 (can't)
829 is 8+2+9=19 (can't)
438 is 4+3+8=15 (can)
51.979 (can't) because it isn't intiger number.
1116 is 1+1+1+6=9 (can)
...
So 339 483 438 1116 1857 57 3417 divisible by 3.
A hypothesis testing is a statistical inference that uses data from a sample to draw conclusions.
<h3>What is hypothesis testing?</h3>
It should be noted that hypothesis testing simply means a statistical act where an assumption is made regarding a parameter.
In this case, a hypothesis testing is a statistical inference that uses data from a sample to draw conclusions. The null hypothesis predicts no effect while the alternative hypothesis states the research predictions.
