1. If OLS estimators satisfy asymptotic normality, it implies that a. they are approximately normally distributed b. they are approximately normally distributed in samples with less than 10 observations large enough sample sizes c. they have a constant mean equal to zero and variance equal to d. they have a constant mean equal to one and variance equal to o 2 In a multiple regression model, the OLS estimator is consistent if a. there is no correlation between the dependent...

Which of the below statements is NOT one of the assumptions of the ANOVA?...
19) ANOVA F test was conducted to test whether the means of five groups are the same against at least one group mean is different. The total number of subjects in five samples were 25. The F ratio (test statistics) was 5.35 a) What is the p-value? (give four decimal places) b) What is your conclusion at 1% significance level? Are all group means the same? In a certain large state prison, the age of prison population is normally distributed with...

Please help with the following multiple choice 1. In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively: a. n and k. b. k and n. c. n − k and k − 1. d. k − 1 and n − k. 2. In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator...

Question 24 3 pts Suppose that the underlying population is normally distributed. From a random sample of 16 individuals from this population, the sample mean is 8 and the sample standard deviation is 10. Suppose someone claims that the true population mean is 3.
