- Accountants at the Tucson firm, Larry Youdelman,CPAs, believed that several traveling executives were submittingunusually high travel vouchers when they returned from businesstrips. First, they took a sample of 200 vo uchers submitted fromthe past year. Then they developed the following multiple regressionequation relating expected travel cost to number of days onthe road (x1) and distance traveled (x2) in miles:y = $90.00 + $48.50x1 + $.40x2The coefficient of correlation computed was .68.a) If Barba ra Downey returns from a 300-miJe trip that took herout of town for 5 days, what is the expected amount she shouldclaim as expenses?b) Downey submitted a reimbursement request for $685. Whatshould the accountant do?c) Should any other variables be included? Which ones? Why?A sample of twenty automobiles was taken, and the miles per gallon (MPG), horsepower, and total weight were recorded. Develop a linear regression model to predict MPG using horsepower as the only indepen- dent variable. Develop another model with weight as the independent variable.

- What are the two types of simple random sample selectionmethods? Which of the two methods is used most often by auditors and why?A company that sells and services car music systems has surveyed residents of the local area surrounding the store as a way to expand their business. They handed out cards at a busy intersection near the store over a two-weekend time period. After a month, they have received 200 responses out of 950 they distributed. The results of this survey will likely be ineffective because a handing out postcards is not a legitimate survey method handing out postcards is not a legitimate survey method b the sample of people may not be the store’s appropriate target the sample of people may not be the store’s appropriate target c not enough people responded not enough people responded D participants did not get a reward for respondingDescribe what panel data is and the reasons for using it Assess the importance of fixed and random effects What is the Hausman Test?
