Answer:
The value is [tex]\r p = 2.9\%[/tex]
Step-by-step explanation:
From the question we are told that
The number of singers is [tex]N = 1542[/tex]
The sample size is [tex]n = 650[/tex]
The number the number of singers who are professional is k = 19
The proportion of professional singers is mathematically represented as
[tex]p = \frac{k}{n}[/tex]
=> [tex]p = \frac{19}{650}[/tex]
=> [tex]p = 0.029 [/tex]
The percentage estimate of singers who are professional is
[tex]\r p = 100 * 0.029[/tex]
[tex]\r p = 2.9\%[/tex]
