Explanation:
From the graph, we can see that the mean of the first graph is given below as
[tex]\mu_1=10[/tex]
The mean of the second graph is given below as
[tex]\mu_2=13[/tex]
The difference between their means are given below as
[tex]\mu_2-\mu_1=13-10=3[/tex]
Hence,
The final answer is
The two distribution has mean that differ by 3 units and different standard deviation
The FIRST OPTION is correct
