Respuesta :
The stem and leaf plot represents the numbers 15, 18, 46, 50, 50, 50, 50, 57. To find the mean, add these up (336) and divide by the number of data points (8). The mean is 42.
The mean of the values in the stem-and-leaf plot is 42.
What is the mean of a set of data?
Mean of a set of data is represented by the ratio of sum of the all data in that data set to total number of data.
Given, a steam value of 1 with leaf values of 5 and 8.
Therefore, the data values are: 15 and 18.
A steam value of 2 represents the data value of none.
A steam value of 3 represents the data value of none.
A steam value of 4 with a leaf value of 6 represents the data value of 46.
A steam value of 5 with a leaf values of 0, 0, 0, 0, 7 represents the data value of 50, 50, 50, 50, 57.
A steam value of 6 represents the data value of none.
A steam value of 7 represents the data value of none.
A steam value of 8 represents the data value of none.
A steam value of 9 represents the data value of none.
Therefore, data values are 15, 18, 46, 50, 50, 50, 50, 57.
Therefore, mean of the values
= (Sum of the data values)/8
= [tex]\frac{15 + 18 + 46 + 50 + 50 + 50 + 50 + 57}{8}[/tex]
= [tex]\frac{336}{8}[/tex]
= 42
