(3 pts) Given sample statistics for two data sets: _ Set A: x 23 Med 22 S 1.2 _ Set B: x 24 Med 29 S 3.1 a) Calculate the

Art [367]

Answer:

Step-by-step explanation:

Given Data:

Set A : x = 23, Med = 22, S = 1.2

Set B : x = 24, Med = 29, S = 3.1

The Formula for Pearson's Index of Skewness (for Median in given data) is:

$Sk_{2} = 3(\frac{x - Med}{S} )$

where,

$Sk_{2} =$ <em>Pearson's Coefficient of Skewness</em>

<em /> $Med =$ <em> Median of Distribution</em>

<em /> $x=$ <em> Mean of Distribution</em>

<em /> $S=$ <em> Standard Deviation of Distribution</em>

<em />

a) Finding Skewness:

For Set A:

$Sk_{2_{A}} = 3(\frac{23 - 22}{1.2} )\\\\Sk_{2_{A}} = (\frac{3}{1.2} )\\\\Sk_{2_{A}} = 2.5$

For Set B:

$Sk_{2_{B}} = 3(\frac{24 - 29}{3.1} )\\\\Sk_{2_{B}} = 3(\frac{-5}{3.1} )\\\\Sk_{2_{B}} = -4.84$

b) Type of Distribution:

For Set A:

As the value of skewness is a positive value (i.e. 2.5). Hence, Set A is right (positively) skewed.

For Set B:

As the value of skewness is a negative value (i.e. -4.84). Hence, Set B is skewed left (or negatively skewed).

c) Which Set can be considered as symmetric?

As the Pearson's Coefficient of skewness for Set A (2.5) is closer to 0 as compared to that of Set B (-4.84). Set A is more closer to that of a symmetric distribution and therefore can be considered as one.

Write a word problem which can be solved using the expression 2x+50

xxMikexx [17]

Answer:

friend this is not a formula

Step-by-step explanation:

ax ± b = c. All problems like the following lead eventually to an equation in that simple form.

Jane spent $42 for shoes. This was $14 less than twice what she spent for a blouse. How much was the blouse?

Solution. Every word problem has an unknown number. In this problem, it is the price of the blouse. Always let x represent the unknown number. That is, let x answer the question.

Let x, then, be how much she spent for the blouse. The problem states that "This" -- that is, $42 -- was $14 less than two times x.

Here is the equation:

2x − 14 = 42.

2x = 42 + 14

= 56.

x = 56

2

= 28.

The blouse cost $28.
