1. Chapter 17A In an attempt to nd factors that can predict the age of male African lions, Whitman et al. (2004) measured the percentage of black pigmentation on the noses of 32 lions of known age in Tanzania. The mean percentage of black on the noses of these lions was 32.2% with a standard deviation of 19.9%, and the mean age was 4.309 years with a standard deviation of 2.67? years. The correlation between these two variables was r = 0.791. a. Calculate the slope and intercept of the regression line for this analysis and write out the complete regression equation. b. Interpret the meaning of the slope. c. Interpret the meaning of the intercept. d. Predict the age of a lion with a nose that is 50% black. 55 e. Calculate the model t statistic for this regression equation and interpret it in context
