Question

a nationally representative survey of 1864 adults ages 18 was taken october 3-6, 2013. it was conducted in english on land line and cell phones. photos and videos have become an integral part of the online social experience. in a new survey conducted by pew research center's internet project, more than half of internet users post or share photos or videos online. our latest data shows: 599 of 927 adult internet users post original photos or videos online that they themselves have created. we call them creators and their number has grown from 46% of internet users last year. 569 of 937 adult internet users take photos or videos that they have found online and repost them on sites designed for sharing images with many people. we call them curators and their number has grown from 41% of internet users last year. do the chosen samples suggest that the percentage of creators is 3% more then the proportion of curators (based on the most recent information we have)? use creators as sample 1 and curators as sample 2.

Answer 1

The chosen samples suggest that the percentage of creators is 3% more than the proportion of curators.

Step-by-step explanation:

To determine if the percentage of creators is 3% more than the proportion of curators, we need to compare the proportions of creators and curators in the samples provided. Sample 1 (creators) consists of 599 out of 927 adult internet users, while Sample 2 (curators) consists of 569 out of 937 adult internet users. We can calculate the proportions for each sample by dividing the number of creators or curators by the total number of adult internet users in each sample.

For Sample 1:

• Proportion of creators = 599/927 = 0.6451 (rounded to 4 decimal places)

For Sample 2:

• Proportion of curators = 569/937 = 0.6071 (rounded to 4 decimal places)

Now, we can compare the proportions. To determine if the percentage of creators is 3% more than the proportion of curators, we subtract the proportion of curators from the proportion of creators and compare the result to 0.03 (3%):

Proportion of creators - Proportion of curators = 0.6451 - 0.6071 = 0.038 (rounded to 3 decimal places)

Since the result is greater than 0.03, we can conclude that the chosen samples suggest that the percentage of creators is 3% more than the proportion of curators.
