Instruction 3-3
the Stem-And-Leaf Display Below Represents the Number of Vitamin

question 93

Short Answer

Instruction 3-3
The stem-and-leaf display below represents the number of vitamin supplements sold by a health food store in a sample of 16 days.
$$\begin{array} { c l } \text { Stem } & \text { Leaves } \\\hline \hline 1 \mathrm { H } & 99 \\2 \mathrm {~L} & 0023 \\2 \mathrm { H } & 567 \\3 \mathrm {~L} & 034 \\3 \mathrm { H } & 568 \\4 \mathrm {~L} & 1\end{array}$$ Note (1): 1H means the "high teens" = 15,16,17,18,or 19;2L means the "low twenties" = 20,21,22,23,or 24;2H means the "high twenties" = 25,26,27,28,or 29,etc.
Note (2): For this sample,the sum of the observations is 448,the sum of the squares of the observations is 13,356,and the sum of the squared differences between each observation and the mean is 812.
-Referring to Instruction 3-3,the five-number summary of the data in this sample consists of ________,________,________,________,________.

Least-squares Method

A statistical technique used to determine the line of best fit by minimizing the sum of the squares of the differences between observed and estimated values.

High-low Method

A technique used in cost accounting to determine the variable and fixed components of a cost by analyzing the highest and lowest levels of activity.

Variable Cost

Expenses that fluctuate in direct proportion to the amount of production or sales, including items like labor and materials.

Machine Hour

A measure of production time, where costs are attributed based on the number of hours a machine is operated.
