data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares th

3241004551 [841]

Answer:

the mean in set B is equal to the mean in set A (option C)

Question:

The question is incomplete as the answer choices were not given.Let's consider the following question:

Data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares the two data sets?

a) median for set A is equal to the median for set B

b) Range for set A is greater than range for set B

c) The mean in set B is equal to the mean in set A

Step by step explanation:

We can describe a data set using four ways:

Center, spread, shape and unusual features.

Let's consider the center and spread.

Center: This is the median of the distribution.

Spread: This is the variation of the data set. If the range is wide, the spread is larger and If the range is small, the spread is smaller.

Rearranging the data set:

A = {30, 32, 32, 33, 40, 44, 45, 50}

B = {28, 30, 34, 35, 42, 43, 46, 48}

From the data:

The median for set A = (33+40)/2 = 73/2= 36.5

The median for set B = (35+42)/2 = 77/2= 38.5

Range = highest value - lowest value

The data ranges from 30 to 50 (range = 20) for A

The data ranges from 28 to 48 (range = 20) for B

Mean for set A = (30+32+32+33+40+4445+50)/8 = 306/8 = 38.25

Mean for set B = (28+30+34+35+42+43+46+48)/8= 306/8 = 38.25

In both data set the mean is equal to 38.25.

Therefore the statement that best compares the two data sets is the mean in set B is equal to the mean in set A (C)

A mountain climber on Mount Everest is at 29,035 feet above sea level a stone at the bottom of the sea is at 1,349 ft below sea

slavikrds [6]

30,384 feet difference between the two, since the climber is 29,035 feet above sea level you take a positive 29,035 and a -1,349 due to being below sea level, you add the two together with the equation 29,035+1349=30,384 feet

A quality report for a production line shows a score of 59 points on a 65- point inspection test. A passing score is 95% complia

Sholpan [36]

Answer:

The line production did not pass inspection

Step-by-step explanation:

* Lets explain how to solve the problem

- To calculate the percentage of one number with respect to another

divide the number by the another number and multiply the answer

by 100 to convert the answer to percentage

- Ex: 15 people out of a total of 25 were female

the percentage of the female is $\frac{15}{25}*100%=60%$

* Lets solve the problem

- A quality report for a production line shows a score of 59 points on

a 65- point inspection test

- A passing score is 95% compliance

- We need to know did the production line pass inspection

∵ The score of the line production is 59 out of 65

∴ The percentage of the score = $\frac{59}{65}*100%=90.77%$

∴ The percentage of the line production is 90.77%

- The passing score is 95% compliance

∵ 90.77% is less than 95%

∴ The line production did not pass inspection
