Answer:
600
Step-by-step explanation:
6000/50=120 groups of 50
120x5=600
We can estimate the expected value of the various percentiles assuming the normal distribution.
The median, 50th percentile, is the mean, 0.785 mm.
Typically we remember ±1 standard deviation is 68% of the probability, so one standard deviation below the mean is 16th percentile (50-68/2) and one standard deviation above the mean is 84th percentile.
The quartiles, 25th and 75th percentile, are about 2/3 of a standard deviation away from the mean. In other words ±.67 standard deviations is 50% of the probability. It's not a commonly remembered number like 68-95-99.7, but perhaps it should be.
The 25th percentile is 0.785 - (.67)(.07) = <span>0.7381 mm.
</span>The 75th percentile is 0.785 + (.67)(.07) = 0.8319 mm.

Answer:
A
Step-by-step explanation:
The commutative property of addition states changing the order of the numbers doesn't not change the sum. The order changed but the numbers stayed the same and as a result the same.
Answer:
See explaination and attachment
Step-by-step explanation:
Average can be defined as a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.
Range can be defined as the difference between the largest and smallest values.
