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
Research Hypothesis
A specific and testable prediction about the relationship between two or more variables.
Alternative Hypothesis
A hypothesis that contradicts the null hypothesis, suggesting that there is a statistical effect or a significant difference in the population.
Credit Cards
Plastic cards issued by banks or financial institutions allowing the cardholder to borrow funds for purchases or cash advances.

Final Answer :
C
Explanation :
The null hypothesis (H0) should be that the mean credit card debt for SJSU freshmen is not different from the average credit card debt of college freshmen (which is $900). In other words, H0: μ = 900. The alternative hypothesis (H1) would be that the mean credit card debt for SJSU freshmen is different from the average credit card debt of college freshmen. Therefore, H1: μ ≠ 900.
