Answer for question A) (A) is there an interaction between the type of course and the length of the course?Answer: Since F =24.2560 > Fcrit, then we_____________ the null hypothesis. Pregunta 8A nationwide company specializing in preparing students for college and graduate school entrance exams, such as the SAT, ACT, andLSAT, had the business objective of improving its ACT preparatory course. Two factors of interest to the company are the length ofthe course (a condensed 10-day period or a regular 30-day period) and the type of course (traditional classroom or online distancelearning). The company collected data by randomly assigning 10 clients to each of the four cells that represent a combination oflength of the course and type of course. The results are organized and presented in the following table:LENGTH OF COURSETYPE OF COURSECondensedRegularTraditional26 1834 2827 2424 2125 1935 2321 2031 29211828 26Online27 2124 2129 3216 1930 2022 1924 2820 2430 2923 25The two-way ANOVA results are (Factor A (columns) is the lenght, factor B (sample) is the type of course )ABDFG1 ANOVA: Two-ractor With Replication23 SUMMARYCondensed Regular Total4traditional5 Count6 Sum7 Average8 Variance10102021927949821.927.924.911.2111 20.9889 24.7263910online11 Count12 Sum10102027021348313 Average2721.324.1514 Variance16.2222 8.0111 20.02891516Tulul17 Count202018 Sum18919219 Average24.4524.620 Variance19.8395 25.2000212223 ANOVA24 Source of VariationdfP-valueI critMS25 Sample5.625015.6250 0.39870.5318 4.113226 Columns0.225010.2250 0.01590.9002 4.113227 Interaction342.22501 342.2250 24.25690.0000 4.113228 Within507.900036 14.10832930 Total855.97503931Level of significance|0.05What are the effects of the type of course and the length of the course on ACT scores?To answer, at the 0.05 level of significance,(A) is there an interaction between the type of course and the length of the course?Answer: Since F=24.2560 > Fcrit, then wethe null hypothesis.Thus, the hypothesis test confirms the interaction evident in the cell means plot. The existence of this significant interaction effectcomplicates the interpretation of the hypothesis tests concerning the two main effects, so we need to perform a One-way Anova tocomplete the analysis.

A) The F-statistic value is 24.2560.
