Answer :
The data of brand C suggests that brand C has the fastest clean time because it has the least average time
How to determine the brand that suggest the fastest?
To do this, we simply calculate the average time of each brand.
From the complete question, we have:
Brand A: 20, 40, 60
Brand B: 30, 60, 90
Brand C: 15, 30, 45
The average is calculated using:
Average = Sum/Count
So, we have:
Brand A = (20 + 40 + 60)/3 = 40
Brand B = (30 + 60 + 90)/3 = 60
Brand C = (15 +30+ 45)/3 = 30
The least clean time is 30 (brand C).
Hence, the data of brand C suggests that brand C has the fastest clean time
