Brittney Brown June 23, 2010 Stat 4210 Homework 2 1. The model y= 158 – 1.14X1 -0.442X2 -13.3X3 could be used to estimate the rating of patient’s satisfaction with treatment received by the age of patient, rating of severity of patient’s illness, and the rating of patient’s level of anxiety. The coefficients have signs in which were expected. The patients’ age, severity of illness, and level of anxiety should all have a negative impact on the patient’s satisfaction with the treatment received. The null hypothesis states that all of the coefficients are equal to zero. The alternative hypothesis states that all of the coefficients are not equal to zero. We reject the null hypothesis and state that the coefficient X1 is not equal to 0 of t=- 5.31, p-value= 0.00. We are 95% confident that the X1 constant is between -0.714 and -1.57. The Adjusted R-squared value is 65.9%, which means 65.9% of the variability in total rating of satisfaction with the treatment received can be explained by the
