Use the table to answer the question.Group A 18 20 46 34 58 31 41Group 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)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 spent shopping for Group A:
(18 + 20 + 46 + 34 + 58 + 31 + 41) / 7 = 36.3 minutes
To find the mean time spent shopping for Group B:
(15 + 21 + 32 + 42 + 29 + 57 + 39) / 7 = 32.3 minutes
The mean times Group A and Group B spent shopping differ by 4.0 minutes.
this is wrong
I apologize for the mistake. Let me recalculate:
For Group A:
(18 + 20 + 46 + 34 + 58 + 31 + 41) / 7 = 33.1 minutes
For Group B:
(15 + 21 + 32 + 42 + 29 + 57 + 39) / 7 = 32.9 minutes
The mean times Group A and Group B spent shopping differ by 0.2 minutes.
this is also wrong think again
I apologize for the oversight. Let's recalculate:
For Group A: Mean = (18 + 20 + 46 + 34 + 58 + 31 + 41) / 7 = 32.4 minutes
For Group B: Mean = (15 + 21 + 32 + 42 + 29 + 57 + 39) / 7 = 32.3 minutes
The mean time Group A spent shopping is 32.4 minutes.
The mean time Group B spent shopping is 32.3 minutes.
The mean times Group A and Group B spent shopping differ by 0.1 minutes.
