Carefully read the Case and Results $($i$.$e$.,$ Results for a clerical test, work sample T$,$ and work sample C$)$ presented in the Applications section of Chapter $7($Measurement$)$ titled $$Evaluation of Two New Assessment Methods for Selecting Telephone Customer Service Representatives.$$ Answer the following questions in complete sentences in a double$-$spaced document with $1-$inch margins $($Note: these questions vary slightly from the questions presented in the text$)$:

Question $1$: Evaluation of Reliability

How do you interpret the reliability estimates for $($a$)$ the clerical test and $($b$)$ the work sample? Are they favorable enough for Phonemin to use each in selecting new job applicants? Be sure to consider the types of reliability data made available to you in your response. Tip: for the clerical test, you have to consider coefficient alpha and test$-$retest reliability; for the work sample you have to consider inter$-$rater reliability $($agreement$).$

Question $2$: Evaluation of Validity

How do you interpret the validity estimates for $($a$)$ the clerical test and $($b$)$ the work sample? Are they favorable enough for Phonemin to use each in selecting new job applicants? Be sure to considering the validity data made available to you in your response. Tip: Be sure to consider the criterion$-$related validity estimates for the clerical test and the work sample as they relate to each of the three performance criteria $($error rate, speed, complaints$).$

Question $3$: Selecting Assessment Methods

Should Phonemin use both the clerical test and the work sample? Why or why not? Tip: Be sure to consider the criterion$-$related validity estimates for the clerical test and the work sample as they relate to each of the three performance criteria $($error rate, speed, complaints$).$

In addition, are both the tactfulness $($T$)$ and concern for customers $($C$)$ interviewer ratings from the work sample needed? Why or why not? If not, which would you retain and why? Tip: This is a tough question, but the data available to you provide an answer. See slide $17$ from my lecture for information related to this issue.

Question $4$: Validation Study Limitations

Describe one limitation from the validation study that should be kept in mind when deciding whether to use the assessments. Limitations are concerns related to the method used in a particular study. No study is perfect; all have limitations$,$ so identify and describe one from this validation study.
