The 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)
The mean time Group A spent shopping is minutes.
The mean time Group B spent shopping is minutes.
The mean times Group A and Group B spent shopping differ by
minutes.
To find the mean time for each group, we first need to add up all the times spent shopping and then divide by the number of people in each group.
Group A:
Total time spent shopping = 40 + 45 + 50 + 55 + 60 = 250 minutes
Number of people in Group A = 5
Mean time spent shopping for Group A = 250 / 5 = 50 minutes
Group B:
Total time spent shopping = 30 + 35 + 40 + 45 + 50 = 200 minutes
Number of people in Group B = 5
Mean time spent shopping for Group B = 200 / 5 = 40 minutes
Now, we can determine the difference in the mean times:
Difference = |Mean time for Group A - Mean time for Group B|
Difference = |50 - 40|
Difference = 10 minutes
Therefore, the mean time Group A spent shopping is 50 minutes, the mean time Group B spent shopping is 40 minutes, and the mean times Group A and Group B spent shopping differ by 10 minutes.
