Answer to Problem 27PFA

Range is 433 and interquartile range is 215

Explanation of Solution

Given information:Weekly pay of 10 employees,

$54, $278, $70, $159, $482, $49, $205, $70, $386, $63

Formula Used:Range is,

  Range=MaxValueMinValue

Lower quartile is

  Q1=(n+1)14

Upper quartile is,

  Q3=(10+1)34

Interquartile range is,

  IQR=Q3Q1

Calculation:

For range substituting values in the range formula,

  Range=48249

On solving,

  Range=433

Rearranging the data in ascending order,

49, 54, 63, 70, 70, 159, 205, 278, 386, 482.

For lower quartile substituting the value,

  Q1=(10+1)14

On solving,

  Q1=2.75

On rounding off,

  Q13

Substituting the value of 3rd observation,

  Q1=63

Hence, lower quartile is 63.

For upper quartile substituting values,

  Q3=(10+1)34

So,

  Q3=334

On solving,

  Q3=8.25

On rounding off,

  Q38

Substituting the value of 8th term,

  Q3=278

Hence, upper quartile is 278.

For interquartile range substituting the values,

  IQR=27863

On solving,

  IQR=215

Hence, interquartile range is 215

Conclusion:Range is 433 and interquartile range is 215

Answer to Problem 27PFA

Mean is 181.6, median is 114.5 and mode is 482.

Explanation of Solution

Given information: Weekly pay of 10 employees,

49, 54, 63, 70, 70, 159, 205, 278, 386, 482.

Formula Used:

Mean is,

  x¯=xn

Median is,

  M=(n2)+(n2+1)2term

Mode is the maximum value of a dataset

Calculation:

For mean, substituting the values,

  x¯=49+54+63+70+70+159+205+278+386+48210

So,

  x¯=181610

On solving,

  x¯=181.6

Hence, Mean is 181.6

For median, substituting the values,

  M=(102)+(102+1)2term

On solving,

  M=5th+6th2term

Substituting the value,

  M=70+1592

On solving,

  M=114.5

Hence, Median is 114.5

For mode,

482 is the mode, since it’s the maximum value.

Conclusion:Mean is 181.6, median is 114.5 and mode is 482.

c.

To determine

To identify any outliers, if present.

Answer to Problem 27PFA

There are no outliers present in the given data.

Explanation of Solution

Given information:

Weekly pay of 10 employees,

49, 54, 63, 70, 70, 159, 205, 278, 386, 482.

Concept Used:Outliers definition.

Calculation:

Evaluating the given data, no observation lies at an abnormal distance.

Hence, there are no outliers in the given set of data.

Conclusion:There are no outliers present in the given data.

d.

To determine

To calculate standard deviation.

d.

Expert Solution

Answer to Problem 27PFA

Standard deviation is

Explanation of Solution

Given information:Weekly pay of 10 employees,

49, 54, 63, 70, 70, 159, 205, 278, 386, 482.

Mean is 181.6

Formula Used:Standard deviation is,

  sd=(xx¯)2n

Calculation:

Substituting the values, sd= (49181) 2 + (54181) 2 + (63181) 2 + (70181) 2 + (70181) 2 + (159181) 2 + (205181) 2 + (278181) 2 + (386181) 2 + (482181) 2 10

On solving,

  sd=(132)2+(127)2+(118)2+(111)2+(111)2+(22)2+(24)2+(97)2+(205)2+(301)210

So,

  sd=21521410

On solving,

  sd=146.70

Hence, Standard deviation is 146.70

Since, standard deviation is high it implies that the observations are scattered over a large range of values.

Conclusion:Standard deviation is 146.70
