Answer: C
The value n represents the number of trials in the binomial distribution. As you increase the number of n, you are increasing the number of bars that would be in your distribution. In effect, you are making it look more and more like a simple bell curve as you increase the number of bars, because they are getting closer together.
A rate is always a ratio.
The denominator is always time.
The key to solving this is to look at the 24 and the 28. First, look at option <span>A.4:74:7
To have 28 equal to 7, you need to divide by 4. But 24 divided by 4 equal 6, so option A doesn't work.
Option B, </span><span>12:1612:16. To have 24 equal to 12, divide by 2. But 28 divided by 2 is 14, not 16. Option B doesn't work either.
Now Option D. </span><span>48:5848:58 To have 24 equal to 48, multiply by 2. But 28 multiplied by 2 is 56, not 58. Option D does not work.
This only leaves option C.</span>
