Answer: If the level of confidence is increased without changing the sample size then<em> </em><u><em>The margin of error will decrease because the critical value will decrease. The decreased margin of error will cause the confidence interval to be narrower.</em></u>
where;
<em>Margin of error = Critical value × Standard deviation</em>
<em>Here, it can be duly noted that Margin of error has a positive relation with critical value, i.e </em><u><em>The margin of error will decrease because the critical value will decrease.</em></u>
<u><em>whereas;</em></u>
The confidence interval is <em>the value ± the margin of error.</em>
<em>Therefore, </em><u><em>the decreased margin of error will cause the confidence interval to be narrower.</em></u>
Answer :6x + 5y = 30
5y = 30 - 6x
y = 6 - (6/5) x
So slope = -6/5
Perpendicular line has slope 5/6 (product of the slopes is -1)
So y = 5/6 x + b
Passed through (-6, -7) so -7 = -5 + b
Sp b = -2
So y = (5/6)x - 2
