Jerry took a sample of 4 employees in his office and observed how many hours they each worked one day.

Illusion [34]

The error in Jerry's calculation is 4.84

The number of employees, N = 4

The mean is calculated as:

$\mu = \frac{10+2+4+8}{4} \\\mu = \frac{24}{4} \\\mu = 6$

The formula for the standard deviation is:

$SD =\sqrt{\frac{\sum{(x-\mu)^2}}{N} }$

This can be further calculated as:

$SD = \sqrt{\frac{(10-6)^2+(2-6)^2+(4-6)^2+(8-6)^2}{4} }\\\\SD = \sqrt{\frac{4^2+(-4)^2+(-2)^2+(2)^2}{4} } \\\\SD = \sqrt{\frac{16+16+4+4}{4} } \\\\SD = \sqrt{\frac{40}{4} } \\\\SD = \sqrt{10} \\\\SD = 3.16$

Jerry thinks the Standard Deviation = 8

The true Standard Deviation = 3.16

Error = |True value - Measured value|

Error = |3.16 - 8|

Error = 4.84

The rectangle of x's below is 5/3 of another (original) rectangle of x's

laila [671]

There are 10 rows of 3 colums of "x"'s, so.. 3x10 or 30 "x"s, and we know that's 5/3 of the original... the original will be one whole or 3/3 or 1

thus $\bf \begin{array}{ccllll}
size&x's\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
\frac{5}{3}&30\\\\
\frac{3}{3}&x
\end{array}\implies \cfrac{\frac{5}{3}}{\frac{3}{3}}=\cfrac{30}{x}
\implies
\cfrac{5}{3}=\cfrac{30}{x}$

solve for "x"
