Question 1
A declaration, or claim, about the value of a specific population parameter is known as a(n):
◦
declarative statement.
◦
hypothesis.
◦
parametric inference.
◦
nonparametric inference.
Question 2
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. (Useα= 0.05.)
◦
CV = 16.9190; TS = 10.347; rejectH0
◦
CV = 16.9190; TS = 10.347; fail to rejectH0
◦
CV = 19.0228; TS = 7.828; fail to rejectH0
◦
CV = 19.0228; TS = 7.828; rejectH0
