Answer:
The correct option is 1, 4 and 6.
Step-by-step explanation:
The given two-way table is
WIN LOSS TOTAL
HOME GAMES 6 10 16
AWAY GAMES 3 8 11
TOTAL 9 18 27
Total number of home games won by team is 6 and total number of away games won by team is 3. It means the team is twice as likely to win a home game as they are an away game.
The correct option is 1.
Total number of home games = 16.
Home game won by team is
Option 2 is incorrect.
Total games = 27
Total games won by the team = 9
Total part of games won by team is
Option 3 is incorrect.
The team played a total of 27 games.
Option 4 is correct.
The team won a total of 9 games.
Option 5 is incorrect.
Total home games loose by team = 10
Total away games loose by team = 8
The team lost more home games than away games.
Option 6 is correct.
Therefore the correct option is 1, 4 and 6.
Answer:
Hence, the set that represent a negative linear association between x and y is:
Set A.
Step-by-step explanation:
We are given 4 sets of data as:
<u>Set A </u>
x 1 2 3 4 5 6 7 8 9
y 10 9 8 7 6 5 4 3 2
<u>Set B </u>
x 1 2 3 4 5 6 7 8 9
y 3 4 5 6 7 8 9 10 11
<u>Set C </u>
x 1 2 3 4 5 6 7 8 9
y 8 6 5 4 3.5 3 2.5 2 2
<u>Set D </u>
x 1 2 3 4 5 6 7 8 9
y 1 2.5 2.5 3 4 5 6 8 9
We are asked to determine the set which represent negative linear association between x and y?
- Clearly in Set B and Set D the values of y keeps on increasing as the value of x increases; hence they both represent a positive linear association between x and y.
- In set C the relationship is non-linear though it is negative.
- Clearly in Set A we could see that the the y is related to x as:
y=11-x or y= -x+11.
Hence, clearly we could see that the relationship is linear and also negative as the value of y keeps on decreasing with increasing x.
Hence, the set that represent a negative linear association between x and y is:
Set A.
Slope....y=mx+b
slope of a line........y2-y1
