The table shows the times and and and spent shopping by two different different groups. Find them mean times each group Spent shopping then determine the difference in the meantime around your answers to one decimal place
Group A: 2.5 hours, 3 hours, 2 hours, 2.5 hours
Group B: 4 hours, 3.5 hours, 4 hours, 3.5 hours
Mean time for Group A = (2.5 + 3 + 2 + 2.5) / 4 = 2.5 hours
Mean time for Group B = (4 + 3.5 + 4 + 3.5) / 4 = 3.75 hours
Difference in mean time = 3.75 - 2.5 = 1.3 hours
Therefore, the mean time Group A spent shopping is 2.5 hours, the mean time Group B spent shopping is 3.75 hours, and the difference in mean time is 1.3 hours.
