Arandomized study compared two different techniques for improving one's memory. the treatment group using technique a reported that the subjects were able to memorize a mean of 8.9 words. the treatment group using technique b reported that the subjects were able to memorize a mean of 12.1 words. 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? the difference of the means is significant because the re-randomizations show that it is outside the range of what could happen by chance. 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. the difference of the means is significant because the re-randomizations show that it is within the range of what could happen by chance. 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.
