(a)
The median of the data
(a)
Answer to Problem 3CYU
Median:
Explanation of Solution
Given:
The given data is
Calculation:
The given data can be written as:
3, 4, 5, 8, 8, 9, 9, 10, 11, 14, 15, 15, 15, 15, 15, 19, 20, 20, 28, 59
Median = The exact middle value of the data when arranged from least to greatest
Order the data from least to greatest: 3, 4, 5, 8, 8, 9, 9, 10, 11, 14, 15, 15, 15, 15, 15, 19, 20, 20, 28, 59
As, the total number of observations are 20 (even), median will be 10th value + 11th value/2.
Median =
(b)
The mode of the data
(b)
Answer to Problem 3CYU
Mode:
Explanation of Solution
Given:
The given data is
Calculation:
The given data can be written as:
3, 4, 5, 8, 8, 9, 9, 10, 11, 14, 15, 15, 15, 15, 15, 19, 20, 20, 28, 59
Mode = The most frequent value in the given data set
So, Mode of the given data is 15.
(c)
The difference between the greatest amount of pasta and least amount of pasta consumed
(c)
Answer to Problem 3CYU
The difference between the greatest amount of pasta and least amount of pasta consumed is
Explanation of Solution
Given:
The given data is
Calculation:
The given data can be written as:
3, 4, 5, 8, 8, 9, 9, 10, 11, 14, 15, 15, 15, 15, 15, 19, 20, 20, 28, 59
Least amount of pasta consumed = 3 lb
Greatest amount of pasta consumed = 59 lb
The difference between the greatest amount of pasta and least amount of pasta consumed = 59 lb − 3 lb
= 56 lb
