DevoreStat9 1.E.058. (3210816) Question Details A company utlizes two different machines to manufacture parts of a certain type. During a single shift, a sample of n 20 parts produced by each machine is obtained, and the value of a particular critical dimension for each part is determined. The comparative boxplot below is constructed from the resulting data. 1· Machine Dimension 85 95 105 115 Compare and contrast the two samples. (Select all that apply.) A typical value is much larger for machine 2 than for machine 1. The only outlier that exists is from machine 2. The only outilier that exists is from machine 1. A typical value is much larger for machine 1 than for machine 2. Machine 1 and machine 2's sample values have about the same amount of variation. Machine 2's sample values have considerably more variation than machine 1's sample values. There are no outiers present. A typical value seems to be about the same for the two machines. Machine 1's sample values have considerably more variation than does machine 2's sample values.Explanation / Answer
Answer:
Correct alternatives are listed below:
The only outlier that exists is from machine 1.
Machine 2’s sample values have considerably more variation than machine 1’s sample values.
A typical value seems to be about the same for the two machines.
Explanation:
From given box plots for machine 1 and machine 2, it is observed that spread for machine 1 is less than spread for machine 2. Outlier is exists for machine 1 only. Outlier is not exists for machine 2. Variation pattern is not same for machine 1 and 2. Also, range for observations for machine 1 and machine 2 is very different. A typical value or median for the given two box plots are very closer to each other.
