Answer:
Mean = 4.11; Median = 4.44
Explanation:
Using a graphing calculator, enter the values into the first list. Then run one-variable statistics on the list.
By hand, to find the mean, add together all of the values:
3.25+3.25+3.66+3.83+4.57+4.52+4.74+4.69+4.44 = 36.95
Divide by the total number of data points, 9:
36.95/9 = 4.11
To find the median, order the data from least to greatest:
3.25, 3.25, 3.66, 3.83, 4.44, 4.52, 4.57, 4.69, 4.74
The middle number is 4.44.
Mean is the average of the data set and medium is the middle value of the data set when the data is written as the least to the greatest value.The mean of the given table to the nearest hundredth is 4.11 and the medium of the given table to nearest hundredth is 4.44.
Given information
The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010.
Total number of terms is 9.
Mean is the ratio of the sum of values of total number of terms in the given data set to the total terms. Mean is the average of the data set.
Mean of a data set can be given as,
[tex]m=\dfrac{\sum n}{n} [/tex]
Here [tex]n[/tex] is the total number of terms in the table.
Put the values given in the table,
[tex]m=\dfrac{3.25+3.25+3.66+3.83+4.57+4.52+4.74+4.69+4.44}{9} \\ m=\dfrac{36.95}{9} \\ m=4.106[/tex]
Thus the mean of the given table is 4.106.
The mean of the given table to the nearest hundredth is 4.11.
Medium is the middle value of the data set when the data is written as the least to the greatest value.
The ascending order of the values given in the table is,
3.25, 3.25, 3.66, 3.83, 4.44, 4.52, 4.57, 4.69, 4.74.
The middle value of the above order is 4.44. Thus the medium of the given table to nearest hundredth is 4.44.
Hence, the mean of the given table to the nearest hundredth is 4.11 and the medium of the given table to nearest hundredth is 4.44.
