Run a regression analysis to predict customer satisfaction using actual elapsed time and

departure delay. Put your output on a new worksheet. Name this worksheet

$$Regression$.$ Using that output, answer the following questions. Put your responses on

the worksheet with the output:

a$.$ Are both independent $($predictor$)$ variables appropriate $($p$-$values less than

$0\mathrm{.}05)?$

b$.$ If not, rerun the analysis using the best variable. Name this worksheet

$$Regression$2.$

c$.$ What is the equation from the appropriate analysis?

d$.$ Based on the F$-$significance and Adjusted R Squared values, is this a good way to

predict the satisfaction of passengers? Why or why not?
