The maximum height of a normal curve corresponds to the of a normal distribution. a) range b) mean c) standard deviation d) statistical significance

Option 'B' is correct.

Step-by-step explanation:

The maximum height of a normal curve corresponds to the 'mean' of a normal  distribution.

Because at the maximum height the normal curve is to be divided and marked it as

On the left hand side of mean , there are marked as

On the right hand side of mean, there are marked as

Hence, the maximum height to a normal curve is "Mean".

Therefore, Option 'B' is correct.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
