Your answer is 4 I hope this help
Answer is 127 mm :)
because it's 12.7 cm,
so 127 mm
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.

It is not because it doesn’t have a length of 90 which is a right triangle
hope this helps
stay safe
brainliest is appreciated, I only need 2 more to level up :))))
