Which set of four test scores would have the biggest difference between the mean and the median? A. 32, 85, 89, 91, 92, 92 B. 72

postnew [5]

Answer:

A. 32, 85, 89, 91, 92, 92

Step-by-step explanation:

A. 32, 85, 89, 91, 92, 92

Mean

$\bar{x}=\dfrac{32+85+89+91+92+92}{6}\\\Rightarrow \bar{x}=80.167$

Since the number of scores is 6 which is an even number the median will be of the form $\dfrac{x_{n/2}+x_{(n/2)+1}}{2}$

Median

$\dfrac{89+91}{2}=90$

Difference of mean and median = $|80.167-90|=9.83$

B. 72, 78, 79, 80, 82, 82

Mean

$\bar{x}=\dfrac{72+78+79+80+82+82}{6}\\\Rightarrow \bar{x}=78.83$

Median

$\dfrac{79+80}{2}=79.5$

Difference of mean and median = $|78.83-79.5|=0.67$

C. 65, 70, 75, 80, 85, 90

Mean

$\bar{x}=\dfrac{65+70+75+80+85+90}{6}\\\Rightarrow \bar{x}=77.5$

Median

$\dfrac{75+80}{2}=77.5$

Difference of mean and median = $|77.5-77.5|=0$

D. 30, 34, 39, 41, 48, 50

$\bar{x}=\dfrac{30+34+39+41+48+50}{6}\\\Rightarrow \bar{x}=40.33$

Median

$\dfrac{39+41}{2}=40$

Difference of mean and median = $|40.33-40|=0.33$

So, A has the maximum difference of 9.83 between the mean and the median.

If PN=29cm and MN=13 , then PM=?

HACTEHA [7]

*see attachment for the figure referred to

Answer/Step-by-step explanation:

1. PN = 29

MN = 13

PM = ?

$PN = PM + MN$ (Segment addition postulate)

$PN - MN = PM$ (subtract MN from each side)

$29 - 13 = PM$ (substitute)

$16 = PM$

$PM = 16 cm$

2. PN = 34, MN = 19, PM = ?

$PN = PM + MN$ (sediment addition postulate)

$PN - MN = PM$ (subtract MN from each side)

$34 - 19 = PM$ (substitute)

$15 = PM$

$PM = 15 cm$

3. PM = 19, MN = 23, PN = ?

$PN = PM + MN$ (Segment addition postulate)

$PN = 19 + 23$ (substitute)

$PN = 42 cm$

4. MN = 82, PN = 105, PM = ?

$PN = PM + MN$ (segment addition postulate)

$PN - MN = PM$ (subtract MN from each side)

$105 - 82 = PM$ (substitute)

$23 = PM$

$PM = 23 cm$

5. PM = 100, MN = 100, PN = ?

$PN = PM + MN$ (Segment addition postulate)

$PN = 100 + 100$ (substitute)

$PN = 200 cm$
