Question

What kinds of people actually read printed information on the packaging before purchasing a product? As part of a larger study on the influence of product packaging on purchase decisions, a survey of 250 citizens of Sarajevo asked if they observed printed information before purchasing a product (Poturak, 2014). Assume that the sample was a simple random one. The data are displayed in the table showing the age group of the individuals in the survey and their response to whether they observed printed information while purchasing a product. The first number in each cell is the observed count, and the second number is the expected count under the assumption that age group and observing printed information are independent. The total number of responses is 249 because one person chose not to answer. Calculate the contribution to the chi-square statistic of the number of individuals in the survey aged 20 - 22 who strongly disagreed about whether they observe packing information before purchasing items. Give your answer precise to two decimal places.
