Is HDTV ownership related to quantity of purchases of other electronics? A Best Buy retail outlet collected the following data for a random sample of its recent customers. At a = 0.10, is the frequency of in-store purchases independent of the number of large-screen HDTVs owned (defined as 50 inches or more)? In-Store Purchases Last Month One 16 32 47 95 O Yes O No HDTVs Owned None One Two or More 19 Column Total 52 None Test statistic Degrees of freedom p-value 15 18 Critical value Click here for the Excel Data File (a) The hypothesis for the given issue is Hy: HDTVs Owned and In Store Purchases are independent. O Yes O No More Than One (b) Calculate the chi-square test statistic, degrees of freedom, and the p-value. (Round your test statistic value to 2 decimal places and the p-value to 4 decimal places.) 13 32 64 109 (d) We reject the null hypothesis. Row Total 44 82 130 256 (c) Find the critical value for chi-Square. Refer to the chi-square Appendix E table. (Round your answer to 3 decimal places.)
