There are 10 employees in a particular division of a company. Their salaries have a mean of $70,000, a median of $55,000, and a

Sindrei [870]

Solution:

a. original $\bar{x} =70,000 =\frac{\sum x}{n}$

$\therefore \sum x = 70,000 \times 10 =700,000$

$modified \sum x = 700,000 - 100,000 + 1,000,000 = 1,600,000$

$modified \bar{x} = \frac{1,600,000}{10} =160,000$

b. Median remains the same.

c. $original s^{2}=(20,000)^{2}=400000000=\frac{1}{n-1}[\sum x^{2}- n\bar{x}^{2}]$

$\therefore orig. \sum x^{2} = (10-1)(20000)^{2} + 10(70000)^{2}$

$=52600000000$

$mod. \sum x^{2} = 52600000000-100000^{2} +1000000^{2}$

$=1.0426E+12$

$mod.s^{2} = \frac{1}{n-1} [\sum x^{2} - n\bar{x}^{2}]$

$=\frac{1}{9} [1.0426E+12 - 10 \times 160000^{2}]$

$=87400000000$

$modified s= \sqrt{s^{2}} =\sqrt{87400000000} =295634.91$
