How do I find out the p-value question?

A manager at LLD Records is investigating the company's market research techniques. She learns that much of the market research of college students is done during promotions on college campuses. She also learns that there are other methods of performing market research (for instance, over the phone, in a mall, etc.). In all cases, for each new CD that LLD Records releases, the company solicits an "intent-to-purchase" 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 manager finds some information on a soon-to-be-released CD. The information details the intent-to-purchase scores from each of several groups of college students, with each group being questioned via a different method. Based on this information, the manager is able to perform a one-way,independent-samples ANOVA test of the hypothesis that the mean intent-to-purchase score for this CD is the same no matter the method of score collection. This test is summarized in the ANOVA table below Fill in the missing entry in the ANOVA table (round your answer to at least two decimal places), and then answer the questions below.the missing entry in wna ter the method dieans samaings questioned viformation deta Sum of Squares Source of Degrees of Mean Square Fstatistic Freedom Variation Treatments Groups) Error Groups) Total (Between 5 1359.9 271.98 2.72 (Within 114 11400 100 12759.9 How many intent-to-purchase scores were examined in all? 118 For the ANOVA test, it is assumed that the population variances of intent-to-purchase scores are the same no matter the method of score collection. What is an unbiased estimate of this common population variance based on the sample variances? 100 What is the /p/-value corresponding to the F statistic for the ANOVA test? Round your answer to at least three decimal places Based on this ANOVA, can we conclude that there are differences in the mearn intent-to-purchase scores (for this CD) among the different methods of collection? Use the 0.05 level of significance O Yes O No Clear Undo

Explanation / Answer

You can find the P value by making use of F table

degree of freedom 1= 5 and degrees of Freedom 2= 114

alpha= 0.05

F statistic=2.72

So P value corresponding to F =2.72 , df1= 5 and df2= 114 is  .023242= 0.023. The result is significant at p < .05.
