One group of accounting students took a distance learning class, while another group took the same course in a traditional classroom. At = .10, is there a significant difference in the mean scores listed below?

Exam Scores for Accounting Students
Statistic	Distance	Classroom
Mean scores	x1x1 = 9.4	x2x2 = 10.8
Sample standard deviation	s1 = 2.3	s2 = 2.7
Number of students	n1 = 21	n2 = 21

(a) Choose the appropriate hypotheses. Assume ₁ is the mean score of distance learning and ₂ is the mean score of classroom learning. a. H₀: _{1 2} 0 vs. H₁: _{1 2} < 0 b. H₀: _{1 2} = 0 vs. H₁: _{1 2} 0 c. H₀: _{1 2} 0 vs. H₁: _{1 2} > 0

multiple choice

• a
• b
• c

(b) Specify the decision rule. (Round your answers to 3 decimal places. A negative value should be indicated by a minus sign.)

(c) Find the test statistic t_calc. (Round your answer to 4 decimal places. A negative value should be indicated by a minus sign.)

(d-1) Make a decision.

(d-2) State your conclusion.

(e-1) Use Excel to find the p-value. (Round your answer to 3 decimal places.)

(e-2) Interpret the p-value.
