B has the larger mean 3. The means of A and B are equal4. A has the larger standard deviation5. B has the larger standard deviation 6 The standard deviations of A and B are equalMy answer: 2 and 4
1 answer:
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.
