Given
The plot of normal distributions A and B.
To find: The statements which are true.
Explanation:
It is given that,
That implies,
From, the given graph, it is clear that, the normal distributions A and B has equal mean.
And, the standard deviation of A is larger than the standard deviation of B.
Hence, the answer is options 3 and 4.
3. The means of A and B are equal.
4. A has the larger standard deviation.
