The quality of the service (how promptly customers were served) has a negative impact of the likelihood of Subsay being recommended.

Having a delicious sub (sandwich) has the most positive impact on the dependent variable (likelihood to recommend).

The model is significant.

The R-square tells us:

One of the highest levels of satisfaction is to recommend a brand, or in this case a sandwich store. Subsay wants to determine what service offerings it should focus on to improve the likelihood of the shop being recommended. To do this, they have run a multiple regression. With 'I would recommend Subsay to my friends' as the dependent variable (what the regression will predict). All the service offering items being the independent variables. 

Having run the regression, you should have an R-square of 0.238. You will need to get the regression right to answer the following questions.

What is the standard error of the estimate? (Round to 2 decimal places).

________ of fieldwork means verifying that field workers are submitting authentic interviews.

A motivational technique used when asking survey questions to induce the respondents to enlarge on, clarify, or explain their answers and to help the respondents focus on the specific content of the interview is called ________.

When the frequency in any cell of a cross tabulation table is low (less than 5), it is ________.

The difference between the smallest and largest values of a distribution is called the ________.

Again using 5 as the independent variable, what is the upper limit of the predicted variable? (to 2 decimal places)
