Which of the below statements best explains the situation?
a) The wizard generates static data, Robert needs to run the t-Test again to get new values.
b) Robert’s samples are from the same product, it would be unusual for the values to change, so this is normal and expected.

However, when he clicks OK, a warning message appears, stating that clicking OK will overwrite data in his worksheet. Refer to his screenshot of the error. Which of the following statements explains the cause of this?
a) This is in reference to Bertrand overwriting the Variable Ranges with new sample data, he must specify different ranges.
b) Bertrand has forgotten to rename his spreadsheet; this warning is in reference to the fact that he will lose his old data. He can cancel and use Save As to give the spreadsheet a new name.
c) Running an F-Test produces 3 columns and 10 rows of data which, in the example, will overwrite his old F-Test data.
