Question
In an experiment, the first sample with n1 = 10 has a standard deviation of s1 = 0.5. The second sample with n2 = 8 has a standard deviation s2 = 0.7.
Determine the 98% confidence interval for (s_1/2)/(s_2/2) which is the ratio of the population variance.
the random sample with sizes n1 = 16 and n2 = 25 respectively were taken from two normal populations. the vairance for both samples were s21 = 48 and S22 = 26 respectively. using an appropriate hypothesis, carry out a test to determine whether the variance from the first population is higher than the variance from the second population. use \alpha = 0.05
