(30 pts) We wish to determine a regression equation that relates the length of an infant (in cm) to age (in days), gender and weight at birth (in kg). Below is portion of the regression analysis derived using a software. *Note: under the gender variable: male and female categories are assigned a value of 1 and 0, respectively. SS 316.8866 3 Residual 71.4734 df Coef. Std. Err. Source Model age weight gender intercept 0.4798 0.0980 8 0.4020 1.0454 1.3113 1.9591 19.53 7.7829 a. What is the sample size for this problem? b. Write the estimated regression equation, interpret each slope coefficients, use the proper unit of measurement. c. Test for significance of the Bage, Bweight, and Bgender at the 99% confidence level.
