A Heat Transfer Process Designed to Cool a Large Electric

question 61

Multiple Choice

A heat transfer process designed to cool a large electric motor must maintain the temperature as steadily as possible.The allowable variance for the process is 0.3969.Ten measurements of effluent temperature from the process have a variance of 0.4563.Assuming the underlying distribution is normal, does the sample indicate that the variance for the process is larger than allowed? State the critical value (CV) , test statistic (TS) , and decision from the test.(Use α = 0.05.)

• A) CV = 16.9190; TS = 10.347; reject H₀
• B) CV = 16.9190; TS = 10.347; fail to reject H₀
• C) CV = 19.0228; TS = 7.828; fail to reject H₀
• D) CV = 19.0228; TS = 7.828; reject H₀
