A normal distribution has a mean of 44 and a standard deviation of 8,
We need to find z-score when x=50
To find z-score we use formula
[tex]z=\frac{x-mean}{standard deviation}[/tex]
mean = 44
standard deviation = 8 and x= 50
[tex]z=\frac{50-44}{8}[/tex]
[tex]z=\frac{6}{8}[/tex]
[tex]z=\frac{3}{4}=0.75[/tex]
the z-score for a value of 50 is 0.75
