Answer:
So, the confidence interval is [34.08, 38.72].
Step-by-step explanation:
We know that a random sample of 18 fields of barley has a mean yield of 36.4 bushels per acre and standard deviation of 7.37 bushels per acre.
We have :
We use the Appendix: Critical Values Tables, and we get that:
We calculate the margin of error:
We get the boundaries of the confidence interval:
So, the confidence interval is [34.08, 38.72].
Answer:
Answer:C = 8
Answer:C = 8Step-by-step explanation:
-2(4c+16)^1/4+2=-2
Move the constant to the right and change the sign
-2(4c+16)^1/4= -2-2
transform expression
![- 2 \sqrt[4]{4c - 16} = - 4](https://tex.z-dn.net/?f=%20-%202%20%20%5Csqrt%5B4%5D%7B4c%20-%2016%7D%20%20%3D%20%20-%204)
Divide each side by -2
![\sqrt[4]{4c - 16 } = 2](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B4c%20-%2016%20%7D%20%20%3D%202)
raise both side of the equation by power of 4
4c-16=16
move constant to the right and change the sign
4c=16+16
4c=32
THEN DIVIDE BOTH SIDES BY 4
C = 8
-9
the coefficient of a term is the number in front of the letter
I think its B -34.5<x because x is an unidentified factor and 6/10 is probably greater than this number .
