(Remember to specify nesw as the probability weight.) The spend8 variable has a sample mean of ______. Make sure you use [pw=nesw] so your results are nationally representative. There is a probability of .95 that spend8’s true population mean falls between a score of ______ at the low end and a score of ______ at the high end. A student researcher…

One True Love by Educational Level A study is conducted in which people were asked whether they agreed or disagreed with the statement that there is only one true love for each person. The table below gives a two-way table showing the answers to this question as well as the education level of the respondents. A person's education is categorized as HS (high school degree or less), Some (some college), or College (college graduate or higher). Is the level of a person's education related to how the person feels about one true love? If there is a significant association between these two variables, describe how they are related. chi-square statistic = i p-value = HS Some College Total Agree Disagree 556 469 Don't know Total 364 166 15 29 198 791 27 935 664 1016 728 1816 71 2615 Round your answer for the chi-square statistic to one decimal place, and your answer for the p-value to three decimal places.
