Using the Empirical Rule, it is found that standard deviation of the sample proportions is of 0.058.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
0.684 and 0.916 is within 2 standard deviations of the mean(below and above), hence there are 4 standard deviations between these measures, so:
4s = (0.916 - 0.684)
s = (0.916 - 0.684)/4
s = 0.058.

Hello!
452.84 rounded to the nearest hundreds place is 
___________________________________________________________
452.84
The number in the hundreds place is 4. When the question asks you to round to the nearest hundreds place, it simply means to round <em>that number </em>either up or down. For example, if the number were 449.84, you would round to 400, as that would be the nearest hundred. Since the digit in the tens place was 5, we rounded <em>up. </em>
