A Researcher Conducted an Analysis That Supported the Research Hypothesis

Multiple Choice

A researcher conducted an analysis that supported the research hypothesis that SJSU students spend less on textbooks than the average California college student. As a result of this finding, imagine you hypothesize that SJSU freshmen owe less on their credit cards than the average college freshman. To test this hypothesis, a group of college students are asked, "If you have your own credit card(s) , how much do you currently owe on them?" The responses of some of the students in this class are summarized as: N = 25 = 834.53
S = 169.40
According to a recent study, the average college freshman owes $900 on their credit cards (Arano, 2006) . Therefore, in this analysis, how could the null and alternative hypotheses be stated?

A) H₀: μ > 900; H₁: μ < 900
B) H₀: μ ≠ 900; H₁: μ = 900
C) H₀: μ = 900; H₁: μ ≠ 900
D) H₀: μ = 834.53; H₁: μ ≠ 834.53
