Question

An accounting professor wants to know if students perform the same on the departmental final exam irrespective of the accounting section they attend. She randomly selects the exam scores of 39 students from four sections. A portion of the output from conducting a one-way ANOVA test is shown in the accompanying table. Assume exam scores are normally distributed. a. Find the missing values in the ANoVA table. (Round intermediate calculations to at least 4 decimal places. Round "SS to 2 decimal places, "MS" to 4 decimal places and "F to 3 decimal places.) ANOVA Source of Variation Between Groups Within Groups Total df MS p-value 147.38 3 MSTR- 35 MSE- 38 F(3,35) 0.0802 SSE 850.61 b. At the 5% significance level, can you conclude that average grades differ in the accounting sections? O Yes since the p-value is less than significance level O Yes since the p-value is not less than significance level O No , since the p-value is less than significance level O No since the p-value is not less than significance level

Answer 1

a)

Source	SS	df	MS	F	P value
between	147.38	3	49.1267	2.445	0.0802
within	703.23	35	20.0923
total	850.61	38

b)

no since the p value is not less than significance level
