A sample of 7 observations from the population indicated that sample variance s,- is 529. A second sample of 10 observations from the same population indicated that sample variance s2- is 100. Conduct the following test of hypothesis using a 0.05 significance level. Ho : 012 = 022 H1: 01 2 > 02 2 You should use the tables in the book for obtaining the F values. For full marks your answer should be accurate to at least two decimal places. a) State the decision rule. Reject Ho in favour of H1 if the computed value of the statistic is greater than or equal to FR . O Reject Ho in favour of H, if the computed value of the statistic is less than or equal to FR. O Reject Ho in favour of H, if the computed value of the statistic is greater than FR. O Reject Ho in favour of H, if the computed value of the statistic is less than FR. O None of the above b) Compute the right F critical value. FR critical value: 0 c) What is the value of the test statistic? F-Test statistic: 0 d) What is your decision regarding Ho? O There is sufficient evidence, at the given significance level, to reject Ho and accept H1. There is insufficient evidence, at the given significance level, to reject Ho and so Ho will be accepted or at least not be rejected. There is insufficient evidence to make it clear as to whether we should reject or not reject the null hypothesis
