Answer:
b) The Pie Eating Contest would be more skewed
Step-by-step explanation:
Let's begin by drawing out a frequency distribution table for the given information:
<u>Pie Eating Contest</u>
Age Group (Years) Frequency
0 - 19 20
20 - 39 40
40 - 59 60
60 - 79 50
If all 20 people (aged 75 - 79) joined this event, the frequency tables changes to become:
<u>Pie Eating Contest (2)</u>
Age Group (Years) Frequency
0 - 19 20
20 - 39 40
40 - 59 60
60 - 79 70
<u>Chili Cookoff</u>
Age Group (Years) Frequency
0 - 19 30
20 - 39 50
40 - 59 40
60 - 79 10
If all 20 people (aged 75 - 79) joined this event, the frequency tables changes to become:
<u>Chili Cookoff (2)</u>
Age Group (Years) Frequency
0 - 19 30
20 - 39 50
40 - 59 40
60 - 79 30
The graphical representation of each event is attached as a picture
A histogram is skewed if its frequency distribution is biased to one side (either to the left or to the right). This implies that the histogram is not evenly distributed. When the histogram is cut into equal halves, the left side and the right side look unidentical.
A histogram is symmetrical if its frequency distribution is neither biased to the right or to the left. It implies that the histogram is evenly distributed across the left and the right side. When the histogram is cut into equal halves, the left side and the right side look identical.
When we consider the event in which all 20 people join the Pie Eating Contest, the histogram becomes skewed to the right.
When we consider the event in which all 20 people join the Chili Cookoff, the histogram becomes more symmetrical
We will observe that when all 20 people joined the Pie Eating Contest, the histogram becomes more skewed to the right and less symmetrical. On the other hand, if all 20 people join the Chili Cookoff, the histogram becomes more symmetrical and less skewed
We will observe that when all 20 people joined the Pie Eating Contest, the histogram becomes more skewed to the right and less symmetrical. On the other hand, if all 20 people join the Chili Cookoff, the histogram becomes more symmetrical and less skewed
<u>Hence, the correct answer is option b) The Pie Eating Contest would be more skewed</u>
Answer:
11.0
Step-by-step explanation:
Using Pythagoras' identity in the lower right triangle.
let the hypotenuse be x , then
x² = 4² + 9² = 16 + 81 = 97
Within the rectangle, use Pythagoras' identity in the lower right triangle.
let y be the dotted line , then
y² = x² + 5² = 97 + 25 = 122 ( take the square root of both sides )
y = ≈ 11.0 ( to the nearest tenth )
The dotted line is approximately 11.0 units
