Suppose X, Y, Z are iid observations from a Poisson distribution with parameter λ, which is unknown. Consider the 3 estimators T1 = X + Y − Z, T2 = 2X + Y + Z 4 , T3 = 3X + Y + Z 5 . (a) Which among the above estimators are unbiased? (b) Among the class of unbiased estimators, which has the minimum variance?
An auto manufacturer claims that the variance of the gas mileage in a model of a hybrid vehicle is 0.16. A random sample of 30 vehicles has a variance of 0.26. At alpha = 0.05, is there enough evidence to reject the claim? Assume the population is normally distributed.
A new material is being tested for use in the manufacture of electrical conduit, to determine whether it will reduce the variance in crushing strength over the old material. Crushing strengths are measured for a sample of size 16 of the old material and a sample of size 20 of the new material. If it is shown that the crushing strength with the new material has smaller variance, the new material will be used.
Over the past 30 years, the sample standard deviations of the rates of return for stock X and Stock Y were 0.20 and 0.12, respectively. The sample covariance between the returns of X and Y is 0.0096. When testing whether the correlation coefficient differs from zero, the value of the test statistic is t28 = 2.31. At the 5% significance level, the critical value is t0.025,28 = 2.048. The conclusion to the hypothesis test is A. to reject H0; we can conclude that the correlation coefficient differs from zero B. to reject H0; we cannot conclude that the correlation coefficient differs from zero C. do not reject H0; we can conclude that the correlation coefficient differs from zero D. do not reject H0; we cannot conclude that the correlation coefficient differs from zero
A random sample of size n = 12 from a normal pop-ulation has the mean x = 27.8 and the variance s2 = 3.24. If we base our decision on the statistic of Theorem 13, canwe say that the given information supports the claim thatthe mean of the population is μ = 28.5?
Let X1, ..., Xn be a sample from an Poisson population with parameter λ.(a) Find the maximum likelihood estimator for λ.(b) Is the estimator unbiased?(c) Is the estimator consistent?
Suppose that you are given two random variables x and y and you take measurements and obtain x1 = 2.3%, x2 = −7.6%, x3 = 0.1% andy1 =60, y2 =120, y3 =80. Findthelineofbestfity=α+βx. Calculate the correlation coefficient r and perform a left-tailed hypothesis test for r with significance level 10%. Based on this test, should we use this line to find the value of y when x = .5%
The makers of Duracell batteries want to demonstrate that their size AA battery lasts longer than Duracell’s main competitor, the Energizer. Two independent random samples of 100 batteries of each kind are selected. The sample average lives for Duracell and Energizer batteries are found to be X ̄1 = 308 minutes and X ̄2 = 254 minutes with S1 = 84 minutesand S2 = 67 minutes. Is there evidence to substantiate Duracell’s claim that its batterieslast, on an average, longer than Energizer of the same size? Find 95% confidence intervaland make your decision. Given the decision from CI, can you write the p-value range incomparison with α = 0.025?
Two random samples of sizes 10, 13 are taken from types of plastics and tested for breaking strength. The test result is that the average strength of the first type 175 and the average strength of the second type is 160. It is known that the two samples have variances 12, 16. The company decides not to use the first type unless its strength exceeds that of second type by at most 9. Should they use the first type or not? (Assume a=0.1)
One sample with n =8 has a S2 = 6 and a second sample n = 8 scores has a S2 = 10. If the pooled variance is computed for these two samples, then the value obtained will be
Suppose that the number of customer that enter a bank in an hour is a Poisson random variable, and suppose that P(X=0)=0.05. Determine the variance of X.
A soft-drink dispensing machine is said to be out of control if the variance of the contents exceeds 1.15 deciliters. If a random sample of 25 drinks from this machine has a variance of 2.03 deciliters, does this indicate at the 0.05 level of significance that the machine is out of control? Assume that the contents are approximately normallyy distributed.
