A transportation worker takes a simple random sample of 105 toll booth receipts for one day and finds that the mean is $9.45 with a standard deviation of $2.41. What is the 99% confidence interval for the mean amount of all the receipts that day?

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
