[example continued…] A researcher is interested in understanding the smartphone habits of college students in the US. To answer this question, the researcher conducts an online survey of 1000 randomly selected college students from California. 77% of these students reported using their smartphones as soon as they wake up in the morning. If the goal of the study is to discover what percentage of college students in the US use their smartphones as soon as they wake up in the morning, that number would be an example of a _________.

[Example continued…] The personality trait of “Conscientiousness” (someone who is organized, responsible, and can control their impulses) has μ = 120 and σ =9. Test whether ARC students (n = 9, M = 126) differ on Conscientiousness. α = .05. The Critical z score boundaries =  

[Example continued…] The average YouTube user spends 40 minutes per session, using YouTube (μ = 40), and σ is unknown. Test whether ARC students who are YouTube users (n = 16, M = 45, SS = 6000) differ from the average YouTube user on number of minutes spent using YouTube per session. α = .05. SM =

The average YouTube user spends 40 minutes per session, using YouTube (μ = 40), and σ is unknown. Test whether ARC students who are YouTube users (n = 16, M = 45, SS = 6000) differ from the average YouTube user on number of minutes spent using YouTube per session. α = .05. What is the alternative hypothesis (H1)

A one sample t test has n = 12. If using a two-tail test (proportion in two tails combined) with an alpha = .05, the critical t score boundaries =

A normal distribution has μ = 9 and σ = 2. What is the probability of a score greater than 6 from this distribution, p(X > 6)?

Test whether ARC students (n = 9, M = 126) differ on Conscientiousness. α = .05. Does the z score for the sample mean lie in the critical region (beyond the critical boundary)?

What is the correct conclusion based on the following ANOVA result: [F(3,16) = +1.77, p > .05]
