Chapter SH, Problem 13.2.5EP

(a)

To determine

To find: the greatest value

Answer to Problem 13.2.5EP

Here greatest value is $98\sec$ .

Explanation of Solution

Given:

Race Times
Stem	Leaf
$7$	$22359$
$8$	$01146689$
$9$	$348$

  $9|4=94s$

Calculation:

Consider the below stem-leaf plot.

Here it shows the time in seconds.

Find the greatest value.

Stem	Leaf
$7$	$22359$
$8$	$01146689$
$9$	$348$

Here greatest value is $98\sec$ .

Conclusion:

Here greatest value is $98\sec$ .

(b)

To determine

To find: the interval in which most of the values occur

Answer to Problem 13.2.5EP

Hence, Most of the values in the interval of $\left(80,90\right)$

Explanation of Solution

Explanations:

Find the interval in which most of the values occur.

Most of the values in the interval of $\left(80,90\right)$

Conclusion:

Hence, Most of the values in the interval of $\left(80,90\right)$

(c)

To determine

To find: the median value

Answer to Problem 13.2.5EP

Hence, the median is $82.5$

Explanation of Solution

Calculation:

Median is the mean of middle values.

  $\frac{81+84}{2}=82.5$

Hence, the median is $82.5$

Conclusion:

Hence, the median is $82.5$
