To find the mean time each group spent shopping, we add up all the times and divide by the number of values.
For Group A:
Mean = (18 + 20 + 47 + 34 + 58 + 31 + 38) / 7
Mean = 246 / 7
Mean = 35.14
The mean time Group A spent shopping is 35.14 minutes.
For Group B:
Mean = (15 + 21 + 32 + 42 + 29 + 57 + 28) / 7
Mean = 224 / 7
Mean = 32
The mean time Group B spent shopping is 32 minutes.
To find the difference in the mean times:
Difference = 35.14 - 32
Difference = 3.14
The mean times Group A and Group B spent shopping are different by 3.14 minutes.
For Group A:
Mean = (18 + 20 + 47 + 34 + 58 + 31 + 38) / 7
Mean = 246 / 7
Mean = 35.14
The mean time Group A spent shopping is 35.14 minutes.
For Group B:
Mean = (15 + 21 + 32 + 42 + 29 + 57 + 28) / 7
Mean = 224 / 7
Mean = 32
The mean time Group B spent shopping is 32 minutes.
To find the difference in the mean times:
Difference = 35.14 - 32
Difference = 3.14
The mean times Group A and Group B spent shopping are different by 3.14 minutes.
