68. T Birthrates 2015 The table shows the number of live births per 1000 population in the United States, starting in 1965. (National Center for Health Statistics, www.cdc.gov/nchs/) Year 1965 1970 1975 1980 1985 1995 2000 2005 2010 2015 Rate 19.4 18.4 1990 14.8 15.9 15.6 16.4 14.8 14.4 14.0 13.0 12.4 Select Library a. Make a scatterplot and describe the general trend in Birthrates. (Enter Year as years since 1900: 65, 70, 75, etc.) b. Find the equation of the regression line. c. Check to see if the line is an appropriate model. Explain. d. Interpret the slope of the line. e. The table gives rates only at intervals. Estimate what the rate was in 1978. f. In 1978, the birthrate was actually 15.0. How close did your model come? g. The birthrate in 2020 was not yet available when this was written. Predict the birthrate in 2020 from your model. Comment on your faith in this prediction. h. Predict the Birthrate for 2050. Comment on your faith in this prediction. 68.
