Answer to Problem 3E
The individuals described here are 7 anonymous students in an AP Statistics class
Explanation of Solution
Given:
gender | hand | height | Homework time | Favourite music | Pocket change |
F | L | 65 | 200 | Hip-hop | 50 |
M | L | 72 | 30 | Country | 35 |
M | R | 62 | 95 | rock | 35 |
F | L | 64 | 120 | Alternative | 0 |
M | R | 63 | 220 | Hip-hop | 0 |
F | R | 58 | 60 | Alternative | 76 |
F | R | 67 | 150 | rock | 215 |
The individuals described here are 7 anonymous students in an AP Statistics class who are randomly selected to respond to a questionnaire on the first day of class
(b)
To identify: the quantitative variable and the measurement units.
(b)
Answer to Problem 3E
Three variables are quantitative i.e. Height. Homework Time and Pocket Change
Their measurement units are inches, minutes and cents respectively.
Explanation of Solution
Six variables are measured here that describes the students in AP Statistics class. The variables, their type and their measurement units are below.
S.no | name | type | measurement |
Gender | categorical | Male or female | |
Hand | categorical | Right or left | |
Height | quantitative | inches | |
Homework time | quantitative | minutes | |
Favourite music | categorical | Hip-hop, county, rock, alternative | |
Pocket change | quantitative | cents |
Thus from the above table we found that out of six, three variables are quantitative i.e. Height
Homework Time and Pocket Change and their measurement units are inches, minutes and cents respectively.
(c)
To describe: the individual in the highlighted row
(c)
Answer to Problem 3E
The student in highlighted class is a female, is right handed, is 58 inches tall,
Explanation of Solution
The student in highlighted class is a female, is right handed, is 58 inches tall, does her homework in 60 minutes, likes alternative music and has 76 cents pocket change.
