STATS 250-In a recent survey, 62% of the sampled 16- to 24-year
Consider the following quote: “In a recent survey, 62% of the sampled 16- to 24-year-olds asked about preferences for physical products versus digital content said they prefer traditional books over their digital equivalences. If there were no preference (that is, if the true proportion of all consumers who prefer traditional paper books over e-books is 0.50), the chance of observing the result of 62% or something even larger would be only about 0.02. Because 0.02 is less than 0.05, we can conclude a statistically significant preference for traditional books.”For this study, the p-value of the test is:The options are 0.02/0.05/0.62 – > which one?For this study, the significance level of the test is:The options are 0.02/0.05/0.62 – > which one?Which of the following phrases is appropriate for the value of 0.62?
