Complete the statement by filling in the blanks: when constructing a confidence interval, if the level of confidence increases, the margin of error must and the confidence interval will be select one:
a. decrease; wider
b. decrease; narrower
c. increase; wider
d. increase; narrower

Option C) Increase; wider

Step-by-step explanation:

When constructing a confidence interval,

Margin of error =

As the confidence level increases, the value for critical value increases and hence, the margin of error increases.

Confidence interval =

As the margin of error increases, the confidence interval will be wider.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
