Question

Use the given info to answer the question:

Assume that the population average number of movies watched by Millennials in 2018 has not changed from 5.
Under this assumption, if this survey were repeated 10 times, how many times would you expect to incorrectly decide to reject H₀at a 10% significance level?

a. 0 times

b. 1 time

c. 9 times

d. 10 times

According to the Harris Poll, U.S. adults watched an average of 5 movies per year in a theater in 2014. As ticket prices rise, and as digital content
providers such as Netflix, Amazon Prime, and Hulu are becoming more popular with the Millennial generation, a researcher claims that, among all
Millennials, the average number of movies watched in a movie theater in 2018 is less than the stated average of 5 movies per year.
That is, they will test these hypotheses at a 10% level:
Ho:H=5 movies per year
Ha: H< 5 movies per year
Use the RStudio Project hw06-WN21 to analyze the data set moviesperyear, which contains the result of the survey of randomly selected Millennials,
asking them how many movies they watched in a movie theater in 2018. You will need to use R to generate numerical summaries and test output in
order to answer the various parts.
