A large industrial customer complains to its electric supplier that the variance in voltage supplied to its facility exceeds the promised value of 255. The electric supplier takes 30 voltage measurements at differing times of the day and finds a sample variance of 244. Does the sample indicate that the population variance is significantly less than 255? State the critical value (CV), test statistic (TS), and decision from the test. (Useα= 0.10.)

◦

CV = –19.7677; TS = 27.749; fail to rejectH0


◦

CV = 14.2565; TS = 30.307; fail to rejectH0


◦

CV = 19.7677; TS = 27.749; fail to rejectH0


◦

CV = 39.0875; TS = 30.307; fail to rejectH0
