As part of a chemistry class students do experiments weekly. Students work in pairs and combined data is entered into a spreadsheet.
The TA leading the lab notices that for 4 weeks in a row, there are exactly 7 repeated values in the combined data set.
Which of the following correctly explains why this statement is true or false?
"The TA should ignore this regularity and assume it is due to chance".
a. True because this is probably due to chance.
b. True because it is not possible to cheat in an experiment.
c. False because students cheat a lot in chemistry classes.
d. False because the regularity of the identical observations is unlikely.
