LLD Records is a store that specializes in oldefashioned vinyl records. The store's market research of college students is done through several methods, including during promotions on college campuses, via email, on the website, etc. In all cases, for each vinyl record, the company solicits an "intenttopurchase" score from the student, with 1 being the lowest score ("no intent to purchase") and 100 being the highest score ("full intent to purchase"). The store manager finds some information on a newly:r acquired vinyl record. The Information details the intentetoepurchase scores from each of several groups ol' college students, with each group being questioned via a different method. Based on this information, the manager is able to perform a oneway, independentsamples ANOVA test of the hypothesis that the mean intenttopurchase score for this record is the same no matter the method of score collection. This test is summarized in the ANOVA table below. (a) Fill in the missing entry in the ANOVA table (round your answer to at least two decimal places).
