Question 18
A probability distribution for all possible values of a sample statistic is known as a
a)sample statistic
b)sampling distribution
c)parameter
d)simple random sample
Question 10The founders of a proposed streaming service called Flix conducted a survey on a sample of people who indicated that they are "real movie fans." The survey asked people to statehow much they base their choices of which movies to see on ratings websites (such as Rotten Tomatoes and IMDB). The founders will only proceed with the business plan if they haveevidence that more than 60% of real movie fans indicate that ratings websites "strongly influence" their viewing choices.What would a Type I error be if a hypothesis test were performed to determine whether the business plan should move forward? Hint: There is no calculation involved here.a)Conduding that more than 60% of real movie fans indicate that ratings websites "strongly influence" their viewing choices, when the percentage is actually 60% or lower.b)Concluding that 60% or less of real movie fans indicate that ratings websites " strongly influence" their viewing choices, when the percentage is actually 60% or less.c)Condiuding that more than 60% of real movie fans indicate that ratings websites "strongly influence" their viewing choices, when the percentage is actually more than 60%.d) Conduding that 60% or less of real movie fans indicate that ratings websites "strongly influence" their viewing choices, when the percentage is actually more than 60%.
