The average january surface water temperatures (°c) of lake michigan from 2000 to 2009 were 5.07, 3.57, 5.32, 3.19, 3.49, 4.25, 4.76, 5.19, 3.94, and 4.34. the data set has the following statistics:

x = 4.312
2 = 0.577
what is the standard deviation? round to the nearest thousandth.

0.333
0.760
2.077
18.593

Second Option

Step-by-step explanation:

We have the average January surface water temperatures (°C) of Lake Michigan from 2000 to 2009.

5.07, 3.57, 5.32, 3.19, 3.49, 4.25, 4.76, 5.19, 3.94, 4.34

We know that the average of the data is:

We also know that the variance is equal to 0.577.

So by definition the standard deviation is:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

yes i do see that. i say this because i am doing my very best in high school so i can get a scholarship and credits.
