Paladinen [302]

Hello there!
Monday: 9.75 x 4 = 39
Tuesday: 9.75 x 6 = 58.5
Wednesday: 9.75 x 5 = 48.75
Thursday: 9.75 x 5 = 48.75
Friday: 9.75 x 7 = 68.25
Now, add all these together to get the gross pay: 39 + 58.5 + 48.75 + 48.75 + 68.25 = 263.25

Hope I helped!

If one were to compare the median and mean household income in the United States, the two figures would be drastically different

Gekata [30.6K]

Step-by-step explanation:

<h2>The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions, the median is better than the mean because it isn't influenced by extremely large values.</h2>

Find the population standard deviation (σ not S) for the data set: {75,80,90,95,75,85,55,80,90,95}

Marianna [84]

The steps to work out standard deviation is as follows

Step 1: Find the mean of the data

$\frac{75+80+90+95+75+85+55+80+90+95}{10}=82$

Step 2: Subtract the mean from each data value

$75-82=-7$
$80-82=-2$
$90-82=7$
$95-82=13$
$75-82=-7$
$85-82=3$
$55-82=-27$
$80-82=-2$
$90-82=8$
$95-82=13$

Step 3: Add up the answers from step 2 $\sqrt{2.9}=1.7$

$-2+(-2)+7+13+(-7)+3+(-2)+(-2)+8+13=29$

Step 4: Divide the answer is step 3 by the number of data

$\frac{29}{10}=2.9$

Step 5: Square root the answer in step 4

$\sqrt{2.9} =1.7$
