A nationwide survey of college students was conducted and found that students spend two hours per class hour studying. A professor at your school wants to determine whether the time students spend at your school is significantly different from the two hours. A random sample of fifteen statistics students is carried out and the findings indicate an average of 1.75 hours with a standard deviation of 0.24 hours. A) H0 is $\mu$ $\neq$ 2. H1 is $\mu$ = 2. B) H0 is $\mu$ = 2. H1 is $\mu$ $\neq$ 2. C) H0 is $\mu$ = 2. H1 is $\mu$ 2. D) H0 is $\mu$ = 2. H1 is $\mu$ 2.

Question

B) H0 is $\mu$ = 2. H1 is  $\mu$ $\neq$ 2.
C) H0 is $\mu$ = 2. H1 is $\mu$ > 2.
D) H0 is $\mu$ = 2. H1 is $\mu$ < 2.
E) H0 is $\mu$ $\neq$ 2. H1 is $\mu$ > 2.

The null hypothesis (H0) is typically a statement of no effect or no difference, set to test against the alternative hypothesis (H1). In this case, H0 posits that the average study time is equal to 2 hours (the national average), while H1 suggests that the average study time at this school is significantly different (either more or less) than 2 hours.
