use the following information: The Organization for Economic Cooperation and Development(OECD) consists of 20 industrialized countries. For these nations, the prediction equation relating y= child poverty rate (in percentage points) to x = social expenditure as a percentage of grossdomestic product (GDP) was ŷ = 22-1.3x in 2000. In 2000, the actual child poverty rate rangedfrom 2.8% (in Finland) to 21.9% (in the U.S.). Social expenditure as a percentage of GDP rangedfrom 2% (in the United States) to 16% (in Denmark). 2) What is the estimate of the slope (b) in the linear prediction equation provided above9 = 22-1.3x)? Also, interpret the slope.slope:Interpretation:

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 vouchers submitted from the past year. Then they developed the following multiple-regres-sion equation relating expected travel cost to number of days on the road ( x1 ) and distance traveled ( x2 ) in miles:yn = +90.00 + +48.50x1 + +.40x2The coefficient of correlation computed was .68.a) If Donna Battista returns from a 300-mile trip that took herout of town for 5 days, what is the expected amount she shouldclaim as expenses?b) Battista submitted a reimbursement request for $685.
