12 friends. Hope this helps! I would love brainliest answer! :)
Answer:
The standard deviation of given probability distribution is 0.767.
Step-by-step explanation:
We are given the following information in the question:
X: 0 1 2 3 4
P(x): 0.4521 0.3970 0.1307 0.0191 0.0010
Formula:


Formula:


The standard deviation of given probability distribution is 0.767.
You need to use pythagorean’s theorem. so a^2+b^2=c^2.
in this case it would be 6^2+8^2=c2
36+64=100
the square root of 100 is 10
x=10
Answer:
Positive nonlinear association
Step-by-step explanation:
The correlation coefficient is fairly low at 0.28, so there is a positive association, but it is definitely not linear.
(It may not be fair to call it non-linear, either. There seems to be no specific value of correlation coefficient below which you declare there to be "no association.")
Wasn’t able to get the answer Buh I hope you the best of luck bestie
