% Consumers reporting frequency50The Consumer Financial ProtectionBureau conducted in 2015 a largesurvey of consumer experienceswith debt collection (when a debtcollector contacts a consumerregarding an unpaid debt).Consumers with a debt collectionexperience in the past year wereasked how many debts they owedand how often they had beencontacted by a debt collector(frequency per week, "/wk"). Hereare the findings as published.a) The findings on this graph can also be plotted in exactly how many pie charts?b) What percent of consumers with one debt were contacted once a week or more?c) Interpret the graph in the context of the problem.

A study examined the interactions in a children's museum. (Interactions by visitors to the museum included show-and-tell, learning, teaching, refocusing, participatory play, advocating, and disciplining interactions.) Researchers observed a sample of 180 meaningful interactions, of which 86 were led by children and 94 were led by adult caregivers. Complete parts a through d below. a. Give a point estimate of the true proportion of all meaningful interactions in a children's museum that are led by children. The point estimate is. (Type an integer or decimal rounded to three decimal places as needed.)

Project on using MS-Excel in descriptive analysis of data: Assuming that you have conducted a survey in a company for a sample of at least 50 employees, you collected data about employees’ job title, academic qualification, years of experience, and salary of the employee (four variables). Required: a. Input the data about the four variables in MS-Excel sheet. b. Prepare frequency distribution tables for the variables. c. Prepare appropriate graph for each of the frequency tables. d. Prepare a pivot table (cross tabulation) for the two qualitative variables. e. Conduct descriptive analysis for the two quantitative variables (summary measures). f. Find the coefficient of variation (CV) and compare the dispersion of the two quantitative variables.
An educational psychologist is interested in whether using a child’s own name in a story affected attention span while reading. Six children were randomly assigned to read a story under ordinary conditions (using common and generic names). Five other children read versions of the same story, but with each child’s ownname substituted for one of the children in the story. The researcher measured the amount of time (in minutes) each child spent reading the story. The results are shown in the following table. Does including the child’s namemake any difference in attention span? Test the hypothesis at an alpha set to .05, following these steps: a) write the null and alternative hypotheses; b) determine the critical value(s); c) draw the comparison distribution with rejection region(s) shaded; d)use the correct formula to compute the test statistic; e) state the statistical decision; f) state a brief conclusion.
