USe the numbers
Group a: 18, 20, 46, 34, 58, 31, 41
Group B: 15, 21, 32, 42, 29, 57, 39
The table shows the times in minutes spent shopping by two different groups. First find the mean time each group spent shoping. Then determine the difference in the mean times. Round your answer to one decimal place.
Group A: mean = (18+20+46+34+58+31+41)/7 = 32.9 minutes
Group B: mean = (15+21+32+42+29+57+39)/7 = 32.9 minutes
Difference in mean times = 32.9 - 32.9 = 0 minutes
