Question

Paying for music downloads. If you use the Internet, have you ever paid to access or download music? This was one of the questions of interest in a Pew Internet & American Life Project Survey (October 2010). In a representative sample of 755 adults who use the Internet, 506 admitted that they have paid to download music. Let p represent the true proportion of all Internet-using adults who have paid to download music. Compute a point estimate of p.

Answer 1

The point estimate of the true proportion of Internet-using adults who have paid to download music is 0.67, calculated by dividing the number of adults who admitted to paying (506) by the total number surveyed (755).

Step-by-step explanation:

The point estimate of p, the true proportion of all Internet-using adults who have paid to download music, can be calculated using the sample data provided. The point estimate is found by dividing the number of adults who have admitted to paying for music downloads by the total number of adults surveyed. According to the survey from the Pew Internet & American Life Project (October 2010), 506 out of 755 adults paid for music downloads, so the point estimate is 506/755 or approximately 0.67.
