Outlier is the value in the data set which very different from the other values.the difference between the mean of the data, including the outlier and excluding the outliers 0.93. Thus the option 3 is the correct option

Given information-

Shelly runs a 5 k race on the first of each month.

<h3>Mean and Outlier</h3>

Mean is the addition of the given data divided by the total number of the values. Outlier is the value in the data set which very different from the other values.

Total values are 12.The addition s of all the values is,

s=40.55+35.35+41.51+37.48+42.01+40.87+38.76+50.32+36.32+41.59+34.38+42.71

s=481.85

Thus the mean m including the outlier for the given data is,

m=\dfrac{481.85}{12}

m=40.153

The value 50.32 is much bigger than the other data set. Thus 50.32 is a outlier for the given problem. The addition of all the values excluding the outlier is,

s_o=40.55+35.35+41.51+37.48+42.01+40.87+38.76+36.32+41.59+34.38+42.71

s_o=431.53

Now the total values are 11. Thus the mean excluding the outlier is,

m_o=\dfrac{431.53}{11}

m_o=39.23

The difference,

\Delta m=40.153-39.23

\Delta m=0.923

Thus the difference between the mean of the data, including the outlier and excluding the outliers 0.93. Thus the option 3 is the correct option.

I’m confused on this one
Yakvenalex [24]

It would be 10 inches. The length of WZ would usually be stated as the diameter in these cases. As you can see in the picture, 5 inches is our radius and the diameter equals the radius times two (2r or the radius doubled) to give the diameter. 5 x 2 = 10, and 10 would be the answer.
