Answer:
AB = 10; BC = 28.
Step-by-step explanation:
It is given ABCD is a parallelogram. In a parallelogram opposite sides are equal.
AB=DC and AD=BC.
Substituting the given values in terms of x ad y we have:
3y-2=y+6 and 2x-4=x+12
Solving for x and y ,
3y-y=6+2 and 2x-x=12+4
2y=8 and x=16.
y=4 and x=16.
AB=3y-2 and BC=x+12
AB=3(4)-2 and BC= 16+12=28.
AB=10.
The correct answer is AB = 10; BC = 28.
The confidence interval would be wider so that you can be more confident that the parameter you're measuring (eg: population mean mu) is inside the confidence interval.
It's like saying "the treasure is somewhere in the country" which is fairly vague but could be true. To be more confident, you can update it to "the treasure is somewhere on the continent". It's even more vague but it increases the chances of being correct.
