Question 1200853: Question Link Part A- Part D file:///C:/Users/chane/Downloads/mceclip1-1648477918709%20(1).webp
Part A
Estimated RLB in 2005 =
Part B: The county planners found a linear trendline for the RLB data, where year represents the number of years since 2000 (for example, 2003 would be Year 3).
RLB = 639(year) + 22,869
Use this equation to find the predicted number of RLB in 2005.
Predicted RLB in 2005 =
Part C: The actual number of RLB in Bexar County in 2005 was 25,851. Find the percent error of the prediction in Part B. Round to the nearest whole percentage point. If your answer is negative, disregard the negative and enter only the percentage.
Percentage error = %
Part D: Recall from Part C that the actual number of live births in 2005 was 25,851. Suppose the actual number of kindergarten students who enter public schools in Bexar County is typically 93.5% of the number of RLB from five years earlier. Use this information to predict the number of kindergarten students who enrolled in 2010.
Predicted number of kindergarteners in 2010 =
Question Link for Part E- Part F file:///C:/Users/chane/Downloads/mceclip1-1648234934690%20(1).webp
Part E A trendline for the 2008-2011 data is given, where year represents the number of years since 2000 (for example, 2008 would be Year 8).
RLB = 31,816 - 552(year)
Use the trendline model to predict the number of RLB in 2015.
Predicted RLB in 2015 =
Part F: If this trend continues, in what year will the number of kindergarten students in Bexar County schools fall below 20,000? Recall that 93.5% of the RLB in any year attend kindergarten five years later.
Year =
