4)When searching for information online, most people quickly scan a document to determine if it is relevant before taking time to read the whole document. Researchers wondered if people would have an easier time determining if a document was relevant if they first saw a word cloud representation of the document. The researchers chose 10 documents and created a word cloud representation for each of them. The researchers showed the text document to one group of people and the word cloud representation to another group of people. The table below records the average time (in seconds) it took the people in the group to make a relevance decision for each version of the 10 documents. 3 Document 1 2 3 4 5 6 7 8 9 10 Text Version 3.55 2.94 3.72 2.63 2.39 5.36 1.86 2.49 2.76 2.77 Word Cloud Version 2.95 3.04 2.72 1.97 2.17 3.64 1.96 2.04 2.46 2.63 Is there a difference in the average time it takes for people to make a relevant decision regarding the relevance of a document when presented in text or word cloud version? a) Are the data independent or paired? Explain. b) What distribution will the sample statistic have? Explain your answer. c). Find and interpret a 95% confidence interval for the true mean difference in text vs. word cloud relevance decisions during the season. d) Answer the research question with a hypothesis test using = 0.05. e) Does the result of the hypothesis test convince you of the answer to the research question? Explain. A word cloud is a visual representa
