Answer:
- A
- A
- C
- B
Step-by-step explanation:
1) The statement is true. A larger margin of error creates a wider confidence interval, which is more likely to contain the population parameter.
2) The statement is false. A larger sample size decreases the standard error of the sample proportion, which decreases the margin of error.
3) The statement is true. A smaller sample size increases the standard error of the sample proportion, which, for a fixed margin of error, decreases the critical value, z*.
4) The statement is true. One can see from the margin of error formula that the margin of error is inversely proportional to the square root of n.
Answer:
180 = 90 + 52+ a
38 =a
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
180 = 90 + 52+ a
Combine like terms
180 = 142+a
Subtract 142 from each side
180 -142 = 142+ a -142
38 = a
Answer:
The slope is a zero slope. This means that the line is a straight, horizontal line.
Step-by-step explanation:
Use the slope formula.
