Complete Question
The standard deviation of samples from supplier A is 0.4582, while the standard deviation of samples from supplier B is 0.3358. Which supplier would you be likely to choose based on these data and why?
1 Supplier A, as their standard deviation is higher and, thus easier to fit into our production line
2 Supplier B, as their standard deviation is higher and, thus, easier to fit into our production line
3 supplier B, as their standard deviation is lower and, thus, easier to fit into our production line
4 Supplier A, as their standard deviation is lower and, thus, easier to fit into our production line
Answer:
Option 3 is correct
Step-by-step explanation:
From the question we are told that
The standard deviation of A is [tex]\sigma_a = 0.4582[/tex]
The standard deviation of B is [tex]\sigma _b = 0.3358[/tex]
Generally standard deviation defines the deviation element of a data set with respect to the mean of the set
So sample it mean that samples from A deviates more from it mean(the standard value) than the samples from B so the best supplier to chose is B
