So I don't know how to do this. I know how to find the median of numbers. But I have a picture it's like a number line with dots on top of the number.
What is the median life expectancy below? What is the range of life expectancy below?
Number line represents years.
Year. How many dots
74. 1
77. 1
78. 2
79. 2
80. 5
81. 2
82. 4
Median is the middle number in a sorted list of numbers.
In this case:
1 ,1 , 2 , 2 , 5 , 2 , 4
Put them in order:
1 , 1 , 2 , 2 , 2 , 4 , 5
Median is 2
The range is the difference between the largest and smallest values.
In this case Range = 5 - 1 = 4
Bosnian shouldn't I count the years the dots are 2 representing two dots on top of that number
How many deaths?
17
half is 8.5
what year has half below and half above?
80
To find the median life expectancy, you need to arrange the given data in ascending order. The number line shows the years on the horizontal axis, and the number of dots above each year represents the frequency or count of life expectancies.
So let's organize the data in ascending order:
Year: 74 (1 dot)
Year: 77 (1 dot)
Year: 78 (2 dots)
Year: 79 (2 dots)
Year: 80 (5 dots)
Year: 81 (2 dots)
Year: 82 (4 dots)
To find the median, we need to locate the middle value. Since there are 17 total dots, the middle value will be the 9th value in the ordered list. Counting from the beginning, we find that the 9th value is 80. Therefore, the median life expectancy is 80 years.
Now, let's find the range of life expectancy. The range represents the difference between the highest and lowest values. From the ordered list, we can determine that the lowest value is 74 and the highest value is 82. Therefore, the range of life expectancy is 82 - 74 = 8 years.
