distribution

Question

If f(x) is normal distribution with mean 8 and std deviation 1 value of f(x) for x=10 is

1)0.05

2)0.14

3)0.25

4)0.73

Comments

I think for this problem,just use normal distribution formula. and put the value of x.

Answer 1

The probability density of the normal distribution is:

Here $\mu$= Mean or Expectation of the distribution.

The parameter  ​  is its standard deviation  with its variance then .

Given  =1 and   =1.

$\mu$= 8 and x=10

After putting value in the function

f(x)=0.0540.

Hence Answer is (1)0.05.
