The accompanying computer excel output (please see attachment on Blackboard) provides details of data and analysis on the topic of "patient satisfaction". A hospital administrator wished to study the relation between patient satisfaction (Y) and patients' age (X1, in years), severity of illness (X2), and anxiety level (X3).
The output includes a listing of all 46 observations; descriptive statistics for each variable; and, the results of a regression analysis that uses patient satisfaction as the dependent variable, and patient's age, severity of illness, and anxiety level as independent variables.
Evaluate the statistical significance of each of the three slope estimates. This can be done in a very summary way. Use a significance level of 0.05. Note: You can either use the p-value or t-statistics to determine whether the coefficients are significant or not.

Answer:
If the p value or sigma value of a specific variable is less than alpha value of 0.05, then the variable is regarded as significant in explaining the variation of y. Otherwise, if the sigma value is greater than alpha level of 0.05, the variable or coefficient is regarded as insignificant.
