According to my calculations the 30% of 570 is 171
10% of 570 is 57
times that by 3 and you get 171
The outlier is 71.
An outlier in a set of data is the one that is significantly lower or higher than the average of the totals. Whichever number skews the average is the outlier.
In this case, it's 71.

The order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>
<h3>Ordering of numbers</h3>
In order to order the given numbers, we will first have to write them as a percentage as shown.
Given the number below
10/8, 1.2, 0.556, 0.8%
Convert to percentage
10/8 = 125%
1.2 = 120%
0.556 = 55.6%
0.8%
Hence the order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>

Answer:
So about 95 percent of the observations lie between 480 and 520.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviations of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
The mean is 500 and the standard deviation is 10.
About 95 percent of the observations lie between what two values?
From the Empirical Rule, this is from 500 - 2*10 = 480 to 500 + 2*10 = 520.
So about 95 percent of the observations lie between 480 and 520.
