Which normal distribution has a wider​ spread: the one with mean 4 and standard deviation 9 or the one with mean 9 and standard deviation 4​?

Solutions

Expert Solution

The standard deviation explains spread of the distribution.

That is bigger the standard deviation the wider spread of the distribution.

Therefore, distribution with mean = 4 and standard deviation = 9 has wider spread

than the distribution mean = 9 and standard deviation = 4.
