Hi, I am stuck on this problem and I am not sure how to begin this problem.
LLD Records is a store that specializes in oldfashioned 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, through phone surveys, and through instore questionnaires. In all cases, for each vinyl record, the company:r 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 nds the following information for 120I intenttopurchase scores for a newlyr acquired vinyl record. Sample Sample Sample Groups size mean variance On campus 24 61.0 119.0 By mail 24 68.0 108.6 By phone 24 69.0 124.4 By internet 24 67.4 67.4 In a store 24 61.3 111.5 Send data to Excel Based on this information, we can perform a oneway, independentsamples ANOVA test to examine the likelihood that the population mean intenttopurchase scores for the record are the same for these different collection methods. Based on this information, we can perform a oneway, independentsamples ANOVA test to examine the likelihood that the population mean intenttopurchase scores for the record are the same for these different collection methods. (a) Such an ANOVA is summarized in the incomplete ANOVA table below. Fill in the missing cells of the table. (In the table, round your answers for the mean squares and the Fstatistic to at least two decimal places each.) Source of Degrees of Sum of Mean s uare Fstatistic variation freedom squares g X 5) Treatments (between 1436.93 gmUDS) Error (within 12,210.70 gmUDS) Total 13,647.63 (b) What is the pvalue corresponding to the Fstatistic for the ANOVA test? Round your answer to at least three decimal places. (c) Based on this ANOVA, can we conclude that there are differences in the mean intenttopurchase scores (for this record) among the different methods of collection? Use the 0.05 level of signicance.
