## Answer to relevant Questions

Using the context of the previous exercise, explain the difference between the purpose of a 95% prediction interval (PI) for an observation and a 95% confidence interval (CI) for the mean of y at a given value of x. Why ...For prediction intervals, an important inference assumption is a constant residual standard deviation of y values at different x values. In practice, the residual standard deviation often tends to be larger when μy is ...Refer to the previous exercise, for which predicted population growth was 14.18% per decade. Suppose the growth rate is now 15% per decade. Explain why the population size will (a) Double after five decades, (b) Quadruple ...The FL Crime data file on the text CD contains data for all counties in Florida on y = median annual income (thousands of dollars) for residents of the county and x = percent of residents with at least a high school ...The population size of Florida (in thousands) since 1830 has followed approximately the exponential regression = 46(1.036)x. Here, x = year - 1830 (so, x = 0 for 1830 and x = 170 for the year 2000). a. What has been the ...Post your question
