Ok so i'm completly out of ideas and knowledge on how to solve this question any help would be much appreciated

The question is:

The r.v. X is such that X ~ N(μ, 4). A random sample, size n , is taken from the population.
Find the least n such that P(| - μ| < 0.5) >0.95

I took one look at the question, and I pitied you. So much so that I thought I'd post this to bump and pray that someone who is knowledgable comes along soon to help out.
I hate statistics and wish you much luck with that.

Get off this damn forum and play your damn guitar.
