In 2012, Nielsen conducted a study of Netflix use. Respondents were asked what they were primarily watching - movies, TV shows, or both equally. The study showed that 19% of all Netflix subscribers primarily watched TV shows through the service. Nielsen plans to undertake a new study of 1849 subscribers to see if this percentage has increased after the service added many more TV shows.

1. What is the population of interest?

• all current Netflix subscribers
• 1849 current Netflix subscribers
• Netflix use
• all individuals who watch TV shows online

• The proportion of proportion of Netflix subscribers who primarily watch TV shows is 19%..
• The proportion of proportion of Netflix subscribers who primarily watch TV shows has decreased from 19%.
• The proportion of proportion of Netflix subscribers who primarily watch TV shows has increased from 19%.

1. Completely describethe sampling distribution for the sample proportion of Netflix subscribers who primarily watch TV shows when samples of size 1849 are selected.Round any calculated value to four decimal places.

1. Using the distribution described in part c, what is theprobabilityof observing 364 or more subscribers who primarily watch TV shows on Netflix when a sample of 1849 subscribers is selected?

• z-score =(round to 2 decimal places)
• Probability =(round to 4 decimal places)

1. Based on the data collected from the sample, what conclusion can be drawn?

• Because the probability isSelect an answer
