Note:

As per the guidelines, we are only allowed to solve three subparts, please post the other questions as a different question.

A normal distribution is a probability distribution with the mean as μ and standard deviation as σ. 

The sampling distribution is written as:

X~Nμ,σ

a.

For this case,

  • X~N(3,1.9)
