Answer 1

Answer:

A is more consistent than B.

Step-by-step explanation:

                                                             A                        B

Mean                                                    30                      25

Standard Deviation                              4                        6

$Standard Deviation^{2}$                              16                      36

The more consistent is the one having less variance. Therefore, A is more consistent than B.
