The population proportion greater than the number 20 = 72.7%

Step-by-step explanation:

To find : The proportion of the population that is greater than 20.  

Now, the data set of the population has been given explicitly, so the sample is irrelevant.

The data set is given to be :  5, 33, 25, 55, 96, 75, 23, 69, 37, 17, 12

Among the given data set of 11 , The numbers which are greater than 20 are :

{33, 25, 55, 96, 75, 23, 69, 37}  

So, The no. of numbers which are greater than 20 = 8

Hence, The population proportion greater than the number 20 = 72.7%
