Answer 1

Solution :

Consider the given plot of two normal distributions A and B as follows ;

A В

Note that, normal distribution has bell shaped curve which is symmetric about it's mean.

Also observe that both the normal curves are identical. And hence both the normal distributions have same spread. The standard deviations of A and B are equal.

Curve A lies left to that of curve B and hence point of symmetry of curve A is less than that for B.

So B has larger mean.
