Some of this energy will be converted into heat due to the friction between the molecules in the microphone. ... The speaker components that move will gain some heat energy in the process. Finally, the medium through which sound travels, be it air, water or something else, will actually gain heat from the sound.

N a survey of twelve Harbor Business School graduates, the mean starting salary was $93,000, with a standard deviation of $17,00

scZoUnD [109]

Answer: The confidence interval would be (82198.71, 103801.28).

Explanation:

Since we have given that

Mean = $93,000

Standard deviation = $17,000

n = 12 < 30

So, we will use 't-test' to find the 95% confidence interval,

Here , $\alpha =1-0.095=0.05$

and $n-1=12-1=11$

So, according to t table, we get that

$t_{n-1,\frac{\alpha }{2}}=2.200985$

So, interval would be

$\bar{x}\pm t_{n-1,\frac{\alpha {2}}\dfrac{\sigma}{\sqrt{n}}\\\\=93000\pm 2.200985\times \dfrac{17000}{\sqrt{12}}\\\\=93000\pm 10801.2839\\\\=(93000-10801.2839,93000+10801.2839)\\\\=(82198.71,103801.28)$

Hence, the confidence interval would be (82198.71, 103801.28).
