Suppose That K Independently Selected Samples Are Available, Each One $s _ { 1 } , s _ { 2 } , \ldots , s _ { k}$

question 53

Multiple Choice

Suppose that k independently selected samples are available, each one consisting of n observations on a normally distributed variable. Denote the sample standard deviations by $s _ { 1 } , s _ { 2 } , \ldots , s _ { k}$ The values $s _ { 1 } , s _ { 2 } , \ldots \ldots , s _ {k }$ are plotted in sequence on an S chart. The center line of the chart will be at height equals to the

• A) average of the values \(s _ { 1 } , s _ { 2 } , \ldots \ldots , s _ { k }\)
• )
• B) range of the values \(s _ { 1 } , s _ { 2 } , \ldots \ldots , s _ { k }\)
• )
• C) standard deviation of the values \(s _ { 1 } , s _ { 2 } , \ldots \ldots , s _ { k }\)
• )
• D) first quartile of the values \(s _ { 1 } , s _ { 2 } , \ldots \ldots , s _ { k }\)
• )
• E) third quartile of the values \(s _ { 1 } , s _ { 2 } , \ldots \ldots , s _ { k }\)
• )
