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

What is the probability that **x̄ **is above 50.8?

P( **x̄**>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. **
