When small samples are used to estimate a population mean, in cases where the population standard deviation is unknown: Group of answer choices the resulting margin of error for a confidence interval estimate will tend to be fairly small. the t-distribution must be used to obtain the critical value. there will be a large amount of sampling error. None of the above

hope this !

the answer is d

step-by-step explanation:

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
