Responses

Both fast food restaurants have exactly one modal delivery time of 40 minutes.

Both fast food restaurants have the same median delivery time of 40 minutes.

Both fast food restaurants have the same mean delivery time of 40 minutes.

Neither data set contains an outlier.

Answer 1

The false statement is: Both fast food restaurants have the same mean delivery time of 40 minutes.

Fast Food 1 has a mean delivery time of (42+38+37+39+38+40+45+41+40)/9 = 39.11 minutes
Fast Food 2 has a mean delivery time of (40+37+40+41+38+46+41+37+40)/9 = 39.11 minutes

Therefore, both fast food restaurants do not have the same mean delivery time.
