540\(^o\)
550\(^o\)
Correct answer is C
Sum = (5 - ) 180\(^o\)
= (5 - 2) 180\(^o\) = 3 x 180\(^o\)
= 540\(^o\)
The mean of the numbers 15, 21, 17, 26, 18, and 29 is 21. Calculate the standard deviation

Correct answer is C
|
x |
x - \(\overline{x}\))\(^2\) | (x - \(\overline{x}\))\(^2\) |
|
15 21 17 26 18 29 |
-6 0 -4 5 -3 -8 |
36 0 16 25 9 64 |
| \(\sum (x - \overline{x})^2\) = 150 |
Standard deviation = \(\sqrt{\frac{ \sum (x - \overline{x})^2}{n} }\)
= \(\frac{150}{6}\)
= \(\sqrt{25}\)
= 5
