An analysis of variance experiment produced a portion of the accompanying ANOVA table. (You may find it useful to reference the F table at https://ezt.prod.mheducation.com/Media/Connect_Production/bne/jaggia_ess2e/table/table_4.jpg ).

a. Specify the competing hypotheses in order to determine whether some differences exist between the population means.

multiple choice

• H₀: ?_A = ?_B = ?_C = ?_D; H_A: Not all population means are equal.
• H₀: ?_A ? ?_B ? ?_C ? ?_D; H_A: Not all population means are equal.
• H₀: ?_A ? ?_B ? ?_C ? ?_D; H_A: Not all population means are equal.

b. Fill in the missing statistics in the ANOVA table. (Round intermediate calculations to at least 4 decimal places. Round "MS" to 4 decimal places and "F" to 3 decimal places.)
