Answer:
Point estimate is 16 and Margin of error is 9
Step-by-step explanation:
The point estimate is given by the following formula:
Point estimate = (Lower Bound + Upper Bound) / 2
Replacing we have:
Point estimate = (7 + 25) / 2 = 32/2
Point estimate = 16
Now, the margin of error is given by the following equation:
Margin of error = (Upper Bound - Lower Bound) / 2
Margin of error = (25 -7) / 2 = 18/2
Margin of error = 9
The answer is a because it matches perfectly with the question at hand
Answer:
Step-by-step explanation:
Expand parentheses:
Combine like terms:
Subtract 2x from both sides:
Add 4 to both sides:
Divide both sides by 26:
