Consider data X1, X2, ... , XniidBer(0). Consider the followingtwo estimators of 01+E X;Ô, = X, and Ô22+ n1. Compute the Bias of both 6, and 02. Which estimator has lower bias?2. Compute the variance of 01 and 02. Which estimator has lower variance? Hint: com-pute the ratio of Var(01]/Var[02] and see if the ratio is less than, equal to, or greaterthan 1.3. Compute the MSE of 01 and 02 using the results of the previous parts. One way ofshowing an estimator is consistent is by showing that the MSE → 0 as n → xo. Are0, and 02 consistent?

Let x represent the average annual salary of college and university professors (in thousands of dollars) in the United States. For all colleges and universities in the United States, the population variance of x is approximately ?2 = 47.1. However, a random sample of 18 colleges and universities in Kansas showed that x has a sample variance s2 = 86.1. Use a 5% level of significance to test the claim that the variance for colleges and universities in Kansas is greater than 47.1. Find a 95% confidence interval for the population variance. ased on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis?

I have asked this question twice and both times it has been wrong. Answer given F=.82 and .77 both these are incorrect. A bakery is considering buying one of two gas ovens. The bakery requires that the temperature remain constant during a baking operation. A study was conducted to measure the variance in temperature of the ovens during the baking process. The variance in temperature before the thermostat restarted the flame for the Monarch oven was 3.3 for 22 measurements. The variance for the Kraft oven was 4 for 25 measurements. Does this information provide sufficient reason to conclude that there is a difference in the variances for the two ovens? Assume measurements are normally distributed and use a 0.02 level of significance.
