stellarik [79]

Answer:

The value is  \r p  =  2.9\%

Step-by-step explanation:

From the question we are told that

   The  number of singers is  N  =  1542

   The  sample  size is  n  =  650

    The  number the number of singers who are professional is k =  19

The  proportion of professional singers is mathematically represented as

       p  =  \frac{k}{n}

=>      p  =  \frac{19}{650}

=>    p  =  0.029

The  percentage estimate of singers who are professional is

      \r p  =  100 * 0.029

       \r p  =  2.9\%
