Answer:
A. Decrease the reliability level.
Step-by-step explanation:
With the same sample as the only source of information about the population, we can only make the confidence interval narrower by being less conservative about the level of confidence. The lower the level of confidence, the less reliability but the narrower the interval becomes.
If we could take a sample again, a bigger sample size tends to construct in narrower confidence intervals.
Answer:
Step-by-step explanation:
4x + y = - 1 -------------(I)
-5x - 2y = -4 -----------(II)
Multiply the equation (I) by 2 and then add the equations.
(I)*2 8x + 2y = -2
(II) <u>-5x - 2y = -4</u> {Now add and y will be eliminated}
3x = -6
x = -6/3
x = -2
Substitute x = -2 in equation (I)
4*(-2) + y = -1
-8 + y = -1
y = - 1 + 8
y = 7
Answer:
2 and 3 look similar to A
1, 4, 5 and 6 are not similar to A .
hopefully you got it right.
