A poll worker analyzing the ages of voters found that [tex]\mu =65[/tex] [tex]\sigma=5[/tex] the possible voter age at Zx=1.14 will be around 71.
It is given that
[tex]\rm Mean\ \mu=65[/tex]
[tex]\rm standard \ deviation \ \sigma =5[/tex]
[tex]\rm X= Ages\ of \ the \ workers[/tex]
From the Z-score concept, we know that
[tex]Z=\dfrac{x-\mu}{\sigma}[/tex]
[tex]x=\sigma Z+\mu[/tex]
putting the values
[tex]X=5\times 1.14+65=70.7[/tex]
Thus A poll worker analyzing the ages of voters found that [tex]\mu =65[/tex] [tex]\sigma=5[/tex] the possible voter age at Zx=1.14 will be around 71.
