A Multiple-Comparison Procedure for Comparing Four Treatment Means Produced the Confidence

question 22

Short Answer

A multiple-comparison procedure for comparing four treatment means produced the confidence intervals shown below. Rank the means from smallest to largest. Use solid lines to connect those means which are not significantly different. $\begin{array} { l } \left( \mu _ { \mathrm { A } } - \mu _ { \mathrm { B } } \right) : ( 20,32 ) \\\left( \mu _ { \mathrm { A } } - \mu _ { \mathrm { C } } \right) : ( 6,24 ) \\\left( \mu _ { \mathrm { A } } - \mu _ { \mathrm { D } } \right) : ( 3,21 ) \\\left( \mu _ { \mathrm { B } } - \mu _ { \mathrm { C } } \right) : ( - 17 , - 5 ) \\\left( \mu _ { \mathrm { B } } - \mu _ { \mathrm { D } } \right) : ( - 22 , - 6 ) \\\left( \mu _ { \mathrm { C } } - \mu _ { \mathrm { D } } \right) : ( - 13,1 )\end{array}$

A) $\mathrm{B} \overline{\mathrm{CD}} \mathrm{A}$
B) $B C D A$
C) $B C \overline{A D}$
D) $\overline{C D} B A$

• A) \(\mathrm{B} \overline{\mathrm{CD}} \mathrm{A}\)
• B)\(B C D A\)
• C) \(B C \overline{A D}\)
• D) \(\overline{C D} B A\)

Definitions:

Inelastic Demand

A situation where the demand for a product or service does not significantly change in response to a price change, indicating consumers’ willingness to buy regardless of price adjustments.

Log-Linear Form

A mathematical representation where variables are transformed using a logarithm, making multiplicative relationships appear linear.

Elasticity Values

Quantitative measures of elasticity, such as price elasticity of demand or supply, indicating how responsive one variable is to changes in another variable.

Demand Determinants

Factors that influence the quantity of a product or service that consumers wish to buy at various prices.
