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:
no
Step-by-step explanation:
the length and the width in one rectangle are the same as the length and width in a second rectangle, then yes those rectangles must be congruent. If you just mean the lengths of 2 rectangles are equal, but their widths are different, then no those rectangles are not congruent.
The <em><u>correct answer</u></em> is:
The last one.
Explanation:
AAS means "angle-angle-side." It states that if two angles and a non-included side of one triangle are congruent to the corresponding two angles and non-included side of another triangle, then the triangles are congruent.
The only triangle in this list marked as having two congruent angles and a side that is not between them congruent is the last figure.
Answer: 13.5
