PLEASE HELP The table shows the number of practice problems completed in 30 minutes in three samples of 10 randomly selected math students.
Number of practice problems completed in 30 minutes Sample 1 18 15 17 18 13 17 16 16 14 18 Mean = 16.2 Sample 2 21 20 18 20 19 19 20 21 21 20 Mean = 19.9 Sample 3 14 16 18 13 18 16 16 17 19 19 Mean = 16.6 Which statement is most accurate based on the data?
A. A prediction based on the data is reliable, because the means of samples 1 and 3 are very close together.
B. A prediction based on the data is reliable, because there are no noticeable differences among the samples.
C. A prediction based on the data is not completely reliable, because the mean of sample 2 is noticeably higher than the means of the other two samples
D. A prediction based on the data is not completely reliable, because the means of samples 1 and 3 are too close together.โ€‹
