Arandomized study compared two different systems for tracking baggage at an airport. the treatment group using system a reported a mean of 18.5 lost bags per day. the treatment group using system b reported a mean of 16.6 lost bags per day.
to determine if the results are significant, the data are re-randomized and the differences of the means are shown in the dot plot.
what is the best conclusion to make based on the data?
a) the difference of the means is not significant because the re-randomizations show that it is outside the range of what could happen by chance.
b) the difference of the means is significant because the re-randomizations show that it is within the range of what could happen by chance.
c) the difference of the means is significant because the re-randomizations show that it is outside the range of what could happen by chance.
d) the difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.
