Question

Draw a stem-and-leaf plot for the data set. (Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.)

**Data set A:** The annual wages of employees at a
small accounting firm are given in thousands of dollars.

36 | 17 | 31 | 37 | 17 | 23 | 37 | 34 | 35 | 16 | 50 | 60 | 18 |

Answer #1

solution:

the given wages are as follows:

36 17 31 37 17 23 37 34 35 16 50 60 18

arrange the data in ascending order to make it small to largest

16 17 17 18 23 31 34 35 36 37 37 50 60

first of all select the stem:

stem are the 10th place digit in the data set . for example in data value 36, the 10th place is 3 so this is a stem and one's digit i,e, 6 is a leaf.

so diffferent stem of data are as follows

3, 1 , 2 , 5, 6

now appliying the leaf to the related stems

so following is the stem and leaf plot are as

Stem | Leaf |

1 | 6 7 7 8 |

2 | 3 |

3 | 1 4 5 6 7 7 |

none | |

5 | 0 |

6 | 0 |

Organize the following data into a stem-and-leaf display where
the following is true. (Enter numbers from smallest to largest
separated by spaces. Enter NONE for stems with no values.)
179, 213, 170, 170, 211, 174, 144, 179, 178, 214
146, 217, 147, 176, 210, 219, 144, 216, 149, 144
(a) the stem has one digit
Stem 1
Stem 2

Describe how to construct a stem-and-leaf plot from a set of
data. Assume that the data consist of two-digit numerical
values.
Choose the correct answer below.
A.
First, organize the data into several classes, such as 40-49,
50-59, and so on. Then, tally the number of data items in each
class, and determine the percentage of the population occupied by
each class. Draw a circle, and divide the circle into portions
representing the percentage for each class.
B.
The plot...

Here is a data set summarized as a stem-and-leaf plot:
3
00024677779
4

How many data values are in this data set? n=n=
What is the minimum value in the last class?
What is the minimum value in the entire sample?
How many of the original values are greater than 40?
The test scores for two algebra classes are shown in the Stem
and Leaf below.

The following is a small data set of 25
observations. I want you to calculate some statistics by
hand to cement the class material. You can use the regular formula
for the variance or the computational formula - I’m just interested
in the correct result. If you use the computational formula, you
will want to calculate a separate row of each value squared in
order to calculate the Sum(x^2). Excel can be used to solve
this problem.

How long did real cowboys live? One answer may be found
in the book The Last Cowboys by Connie Brooks (University
of New Mexico Press). This delightful book presents a thoughtful
sociological study of cowboys in West Texas and Southeastern New
Mexico around the year 1890. A sample of 32 cowboys gave the
following years of longevity:

Many food products contain small quantities of substances that
would give an undesireable taste or smell if they are present in
large amounts. An example is the "off-odors" caused by sulfur
compounds in wine. Oenologists (wine experts) have determined the
odor threshold, the lowest concentration of a compound that the
human nose can detect. For example, the odor threshold for dimethyl
sulfide (DMS) is given in the oenology literature as 25 micrograms
per liter of wine (µg/l). Untrained noses may...

A set of numbers such as those below is meaningless without some
background information. The INDIVIDUALS here are Newcomb's 66
repetitions of his experiment. We need to know exactly WHAT
VARIABLE he measured, and in WHAT UNITS. Newcomb measured the time
in seconds that a light signal took to pass from his laboratory on
the Potomac River to mirror at the base the Washington Monument an
back, a total distance of about 7400 meters. Just as you can
compute the...
