H₁: O The distribution of computer types is the same for each car type. O Computer type and car type are independent. O Computer type and car type are dependent. O The distribution of computer types is not the same for each car type. c. The test-statistic for this data = d. The p-value for this sample= e. The p-value is Select an answer f. Based on this, we should Oreject the null O accept the null O fail to reject the null (Please show your answer to three decimal places.) (Please show your answer to four decimal places.) g. Thus, the final conclusion is... O There is insufficient evidence to conclude that computer type and car type are dependent. There is sufficient evidence to conclude that computer type and car type are independent. There is sufficient evidence to conclude that the distribution of computer types is not the same for each car type. OThere is insufficient evidence to conclude that the distribution of computer types is not the same for each car type. O There is sufficient evidence to conclude that computer type and car type are dependent.
