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? Assume equal variances because the standard deviations are similar.

Mean scores x1=9.9 x2=10.8

Sample std. dev. s1=2.5 s2=2.6

Number of Students n1=18 n2=18

(a)Choose the appropriate hypotheses. Assume₁is the mean score of distance learning and₂is 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

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

Reject the null hypothesis if t_calc< or t_calc>.

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

t_calc

(d-1)Make a decision.

We reject or do not reject the null hypothesis?

(d-2)State your conclusion.

Wecan or cannot conclude that there is a significant difference in the mean scores of distance learning and classroom learning?
