About 32.34% of the values do not lie between the z-scores of -1.3 and 0.75.
First, we need to find the region between the z-scores.
If you look at a normal distribution table, you will get the following values:
0.75 = 77.34%
-1.3 = 9.68%
Subtraction those gives us the area between the z-scores.
77.34 - 9.68 = 67.66%
Now, just subtract that value from 100% to get the amount outside of the area.
100 - 67.66 = 32.34%

60 x 5 = 300 days
So five half-lifes = 300 days
Starting amount = 500mg
<span>Amount after 1st half-life = 250 mg</span>
<span>Amount after 2nd half-life = 125 mg</span>
<span>Amount after 3rd half-life = 62.5 mg</span>
<span>Amount after 4th half-life = 31.25 mg</span>
<span>Amount after 5th half-life = 15.625 mg</span>
<span>Hence after 300 days, the amount of iodine-125 will be 15.625 mg out of 500 mg.</span>
