Use the table to answer the question. Group A 18 20 46 34 58 31 41 Group B 15 21 32 42 29 57 39The table shows the times, in minutes, spent shopping by two different groups. First find the mean times each group spent shopping. Then determine the difference in the mean times. Round your answers to one decimal place.(2 points)

Answer 1

Mean time for Group A:

(18 + 20 + 46 + 34 + 58 + 31 + 41) / 7 = 38.6

Mean time for Group B:
(15 + 21 + 32 + 42 + 29 + 57 + 39) / 7 = 34.6

Difference in mean times:
38.6 - 34.6 = 4.0

Therefore, the mean time spent shopping for Group A is 38.6 minutes, the mean time spent shopping for Group B is 34.6 minutes, and the difference in mean times is 4.0 minutes.
