Predicting bed census-multiple regression model

Assignment Help Basic Statistics
Reference no: EM1396667

To help schedule staffing and equipment needs, a large hospital uses a multiple regression model to predict its 'bed census' y, the number of beds occupied at the end of each day. Using hospital records from the most recent 30 days, a total of 3 independent variables are used to find the estimated regression model. Let B1, B2, and B3 denote the coefficients of the 3 variables in this model. A computer printout indicates that the error sum of squares (SSE) associated with the model is 60.39 and the corresponding regression sum of squares (SSR) is 9.41. Using a significance level of .10, can you conclude that at least one of the independent variables in the model provides useful (i.e., statistically significant) information for predicting daily bed census?
Perform a one-tailed test. Then fill in the table below.

Carry your intermediate computations to at least three decimal places and round your answers as specified in the table.
