Step-by-step explanation:
From the graph, we can see that the mean of the first graph is given below as
![\mu_1=10](https://img.qammunity.org/2023/formulas/mathematics/college/w9gqdowivyy2tgq18m3tlj111sch5fkiwu.png)
The mean of the second graph is given below as
![\mu_2=13](https://img.qammunity.org/2023/formulas/mathematics/college/yqraqlvfh5moktcvn4136hskyqtpda9m7x.png)
The difference between their means are given below as
![\mu_2-\mu_1=13-10=3](https://img.qammunity.org/2023/formulas/mathematics/college/pf3kncd04h98xx39titwz82awim9gdxawv.png)
Hence,
The final answer is
The two distribution has mean that differ by 3 units and different standard deviation
The FIRST OPTION is correct
