Answer:
The another term for the 4% value is : Margin of error
Step-by-step explanation:
Dr. Cyril conducts a simple random sample of 500 men.
He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%.
Now, the another term for the 4% value is : Margin of error
Means the estimate of father being unsure about his ability would be between 19% and 27%.
When sample size is increased, the margin of error becomes smaller.
Answer: Yes, the answers in the blanks are correct.
Step-by-step explanation: The easiest way to answer this question is to plot the points onto a graph. The point (0,10) is right on the y-axis, so that would be the y-intercept. The best way to find the slope is the rise over run method. The slope 2/5 is correct because it "rises" by 2 units and "runs" by 5 units.
Answer:
A
Step-by-step explanation:
Answer:
y=-2x+5
Slope: -2
y int. 5
Step-by-step explanation:
Convert to slope intercept form
2y-10=-4x
Add 10 to both sides
2y-10+10=-4x+10
Simplify
Divide both sides by 2
Simplify
y=-2x+5
Slope: -2
y intercept: 5
I've answered this before, but only partially. I'm not sure about the second part, but I think the first one is 10
