a.

Explanation of Solution
Given information:
The table that depicts number of jigsaw puzzle pieces and the number of minutes taken by person to complete it.
Graph:
Consider the table that depicts number of jigsaw puzzle pieces and the number of minutes taken by person to complete it.
Let x denote the number of pieces and y denote the time in minutes.
On the coordinate plane plot the ordered pairs.
Interpretation:
When these cross are joined by a line these cross lie on a straight line. There is some relationship between number of pieces and time required to join these pieces.
b.
To describe: The scatter plot between the number of jigsaw puzzle pieces and the number of minutes taken by person to complete itwill show a positive, negative or no relationship.
b.

Answer to Problem 1.6.4EP
The scatter plot between the number of jigsaw puzzle pieces and the number of minutes taken by person to complete itwill show positive relationship.
Explanation of Solution
Given information:
The number of jigsaw puzzle pieces and the number of minutes taken by person to complete it.
When the relationship between two data sets is to be analyzed scatter plot is used.
Consider the table that depicts number of jigsaw puzzle pieces and the number of minutes taken by person to complete it.
Let x denote the number of pieces and y denote the time in minutes.
On the coordinate plane plot the ordered pairs.
When these cross are joined by a line these cross lie on a straight line. There is some relationship between number of pieces and time required to join these pieces.
As the number of pieces increase the time taken also increase.
It is observed that there is a positive relationship between x and y.
Thus, the scatter plot between number of jigsaw puzzle pieces and the number of minutes taken by person to complete itshow a positive relationship.
c.
To describe: The time taken to complete the puzzle with 650 pieces.
c.

Answer to Problem 1.6.4EP
The time taken to complete the puzzle with 650 pieces is approximately
Explanation of Solution
Given information:
The number of jigsaw puzzle pieces and the number of minutes taken by person to complete it.
When the relationship between two data sets is to be analyzed scatter plot is used.
Consider the table that depicts number of jigsaw puzzle pieces and the number of minutes taken by person to complete it.
The time required to join 60 pieces is 20 minutes.
So, the time required to place 1 piece is
The time taken to join 2 pieces is
Therefore, time taken to join 650 pieces is
Thus, the time taken to complete the puzzle with 650 pieces is approximately

- Instructions: Answer each question showing all work. 1. Out of 30 animals at a veterinarian clinic, 8 cats and 4 dogs have been vaccinated. 6 cats and 12 dogs are not yet vaccinated. Create a two-way frequency table to represent the data. 2. Convert the table from number 1 into a two-way relative frequency table. Instructions: Based on the tables created in questions 1 and 2 above, answer questions 3-7. 3. What percentage of cats from the total animals are vaccinated? 4. What is the relative frequency of dogs from the total animals that are not yet vaccinated? 5. What is the conditional frequency of cats that have not been vaccinated? 6.
