Given a normal distribution =50 =5, and given you select a sample of n=100 What is the probability that x is above 50.8 ?

Given a normal distribution μ=50 σ=5​, and given you select a sample of n=100​


What is the probability that is above 50.8​?


​P( >50.8​)=


​( integer or decimal rounded to four decimal places as​ needed.)


A study reports that 36​% of companies in Country A have three or more female board directors. Suppose you select a random sample of 100 respondents.
