Answer:
he correct statements are 5th and 6th.
Step-by-step explanation:
The data set from the dot plot is as follows:
A B
25 25
25 25
25 25
26 26
26 26
26 26
27 26
28 27
28 27
29 27
30 27
31 28
31 28
32 29
33 29
33 30
34 31
35 31
35 32
35 34
Use Excel to compute the value of Mean, Median, and Standard deviation for both the data sets.
Set A:
[tex]\text{Mean}_{A} = 29.7\\\text{Median}_{A} = 29.5\\\text{SD}_{A} = 3.658[/tex]
Set B:
[tex]\text{Mean}_{B} = 27.95\\\text{Median}_{B} = 27\\\text{SD}_{B} = 2.544[/tex]
For a symmetric data, Mean = Median.
For left skewed data, Mean < Median
For both the sets of data Mean > Median.
The standard deviation of set A is more than that of set B.
The mean of set A is 29.7 and the median is 29.5. Both values are quite close to each other.
Thus, the correct statements are 5th and 6th.
