A researcher is studying cancer mortality rates for men in five southern states. In the five states, the sample standard deviation is 6.76 (per 100,000). A 98 percent confidence interval estimate of the population variance is represented by:
a. 5(6.76) / 13.277 and 5(6.76) / 0.297.
b. 5(6.762) / 13.277 and 5(6.762) / 0.297.
c. 4(6.76) / 13.277 and 4(6.76) / 0.297.
d. 4(6.762) / 13.277 and 4(6.762) / 0.297.
e. 4(6.762) / 0.297 and 4(6.762) / 13.277.
