It is false for DCA of fixed effects and random effects a. They are all true. b.In random effects the inference can be extended to treatments that are not experienced and in fixed effects it is not. c. The analysis of variance is performed on the variances for the random effects analysis and on the means for the fixed effects analysis. d. In both it is possible to choose for the factor both the number of levels and the levels why?
We are interested in determining whether or not the variances of the sales at two small grocery stores are equal. A sample of 10 days of sales at Store A and a sample of 12 days of sales at Store B indicated the following. Use a=0.1. Store A n₁ = 10 Store B n₂ = 12 $1 = 60 $2=40 (A) The test statistic is F = 1.50 (B) The test statistic is F= 2.25 (C) The rejection region is F≥2.8962 (D) The rejection region is F≥3.1025

A manager wants to determine if there is a difference in the total amount of time spent workers between workers taking an work from home (WFH) and a work from office (WFO) version of a certain duties. The following table contains the sample sizes of each group, and the rank sums for the Wilcoxon rank-sum test. WFH WFO Sample Size 10 12 Sums of Ranks 94.5 158.5 Specify the competing hypothesis to determine whether the median working time for work from home (WFH) workers differs from the median study time for work from office (WFO) workers. What is the value of the Wilcoxon rank-sum test statistic W? Assuming W follows a normal distribution, what is the value of the corresponding test statistic? At the 1% significance level, what is the decision and conclusion?
Example 11. Find the mean values of two random variables x and y and the correlation coefficient between them when the two lines of regression are given by: 5x + 7y – 22 = 0 and 6x + 2y – 20 = 0. If the variance of y is 15, find the standard deviation of x. -
Let x = age in years of a rural Quebec woman at the time of her first marriage. In the year 1941, the population variance of x was approximately ?2 = 5.1. Suppose a recent study of age at first marriage for a random sample of 41 women in rural Quebec gave a sample variance s2 = 2.9. Use a 5% level of significance to test the claim that the current variance is less than 5.1. Find the value of the chi-square statistic for the sample. (Round your answer to two decimal places.) What are the degrees of freedom?

An experiment where a patient's blood pressure is measured before a treatment (call it X;) and after the treatment (call it Y;). The difference in the blood pressue of each patient, Z; = Y; – X; is also recorded. The sample size n of patients is large. Suppose the true population mean of the patient's blood pressure before treatment is 41 and after treatment is 42, both unknown. Suppose the true population variance of the patient's blood pressue before and after treatment are the same, but unknown. Find an approximate 1-a confidence interval for 12 - 41- 2.
