Chapter 1, Problem 1.17ACB
Disaggregation of annually reported accounting data. Researchers have constructed a new measure of disclosure quality—called disaggregation quality (DQ)—based on the level of disaggregation of financial data items in a firm’s annual reports (Journal of Accounting Research, December 2015). Quantitative DQ values were computed for each of 125,873 firms that had annual balance sheet data from 1973 to 2011 reported on Compustat. One objective is to describe the distribution of the DQ values for firms reported on Compustat.

- In 2019, the United States Department of Education defined a "credit hour" as one hour per week of instruction, and two additional hours of work outside of class. So, for example, a 3 credit hour class should aim to have about 6 hours of outside-of-class work per week.Earlier this semester, I asked students how many hours they spent on the course outside of class time. A couple students provided helpful, but non-numeric, responses, so I omitted them from the data set. Below is a dotplot and summary statistics from the other responses: a)suppose we want to view this data as a sample of students from sections of Math 104. Then: n= xˉ= s= b)List at least one concern you might have about using this sample to do inference on the number of study hours for all students taking Math 104. c)Putting aside the concerns you raised in (b) the Professor is wondering if the sample demonstrates that the amount of work he assigns in the course is reasonable under the federal guidelines for a…arrow_forwardA researcher wants to determine if there is a relationship between income earned by siblings and birth order in families of three siblings.
