Pushpin, a social networking site, sent out a survey to all female users. One of the questions in 2014 was, "Do you cook dinner every day?" More than 35,000 women responded, with 38% responding yes. What can you conclude from the survey? The poll used stratification, so the results tell us little about the population of all adults.
About 38% of women cooked dinner every day in 2014.
Undercoverage occurred, so the results tell us little about the population of all adults.
The sample is too small to draw any conclusions.
None of the previous answers is correct.

In the given context, we can conclude that about 38% of women cooked dinner everyday in 2014.

Option: B

Explanation:

The survey was conducted by a social networking site and on just among the female users of it. So, if we consider the total number of female users as a 100% then out of them 38% responds in favor of the question. So, in this case we can't say that the survey is stratified survey because its only worked on female users.

It's also can't called under coverage because particularly the female users of that sites are targeted not overall female population of world. Even we can't say that sample size is small. Because wherever we will mention the survey result it will be clearly mentioned that there only female users of Pushpin are surveyed.

Undercoverage occurred, so the results tell us little about the population of all adults.

Explanation:

This was targeted to social networking site females, this excludes the population of females who do not use social networking or are unable to. Hope this helps
