Answer:
Step-by-step explanation:
A sample of 300 spare parts produced by a machine contained 48 defectives
Probability of Defectives = 48/300 = 16/100
Another sample of 100 spare parts produced by another machine contained 24 defectives
Probability of Defectives = 24/100
16/100 < 24/100
=> Probability of Defectives from 1st machine is Less
hence 1st Machine is Better
