Answer:
which agrees with answer C in your list of possible answers.
Step-by-step explanation:
We can use the general point-slope form of a line of slope m and going through the point :
which in our case, given the info on the slope (2) and the point (-1, 4) becomes:
Answer:
2.88
Step-by-step explanation:
Data provided in the question
= Population standard deviation = 7 miles per hour
Random sample = n = 32 vehicles
Sample mean = = 64 miles per hour
98% confidence level
Now based on the above information, the alpha is
= 1 - confidence level
= 1 - 0.98
= 0.02
For = 0.01
= 2.326
Now the margin of error is
= 2.88
hence, the margin of error is 2.88
