Answer:
<h2>Option 2 is the right answer.</h2>Step-by-step explanation:
We need to check if the two characteristics, <u>having blue eyes and being deaf are independent of each other or not</u>.
The above two characteristics will be independent if
Now, the probability of having blue eyes is .
The probability that the Dalmatians will be deaf is .
The probability of being deaf with blue eyes is .
Since, 38 is not equals to 42, the two characteristics are not independent.
We are asked to find ratio of two relative intensities. Let's start by rearranging formula for R:
For air-raid siren we have:
For jet engine noise we have:
To find out <span>many times greater is the relative intensity of the air-raid siren than that of the jet engine noise we need to divide these two numbers:
</span>tex] \frac{R_{1}}{R_{2}} = \frac{10^{15}}{10^{12}} =10^{3}=1000[/tex]
For air-raid siren we have:
For jet engine noise we have:
To find out <span>many times greater is the relative intensity of the air-raid siren than that of the jet engine noise we need to divide these two numbers:
</span>tex] \frac{R_{1}}{R_{2}} = \frac{10^{15}}{10^{12}} =10^{3}=1000[/tex]
