Lily Energy Systems manufactures wood-burning heaters and fireplace inserts. One of its systems has an electric blower, which is thermostatically controlled. The blower is designed to automatically turn on when the temperature in the stove reaches 125F and turn off at 85F. Complaints from customers indicate that the thermostat control isn't working properly. The company feels that the thermostat is acceptable if the variance in the cutoff temperature is less than or equal to 175. The company takes a sample of 24 thermostats and finds that the variance equals 289. The calculated chi-square test statistic and the table value for a 0.05 significance level are

A. 35.172, 38.99.

B. 37.983, 35.172.

C. 37.983, 38.076.

D. 38.076, 38.99.
