Question

A confidence interval for mu_1 - mu_2 is (-5, -12). Therefore the statistical conclusion is that the two means are _ _ (equal, different) and that mu_1 is __ __ than mu_2 To use the t-test statistic to test for a difference between the mean of two populations we must assume that both populations are 3. One fundamental assumption in ANOVA procedure is that for each treatment the response variable is normally distribute with _ _ variance. The 2.5 % (one sided) value of the F distribution with 8 in the numerator and 17 in the denominator is In a BRD the k treatments are randomly assigned to the units in each block. Therefore, each treatment appears once in every In a Completely Randomized Design the ANOVA table specifies 3 sources of variation: 1) Treatments 2) _ 3) Total. In the Analysis of Variance procedures learned in class, the response variable is _ _ (quantitative, qualitative). A Randomized Block Design is applied to a situation with 10 blocks and 4 treatments. Therefore the data contain __ measurements. In every ANOVA analysis the symbol the SS (Total) equals sigma y^2 - CM _ True __ (True, False) A researcher has analyzed the effect of 5 treatments to grow wheat. The experimental unit is the plot where the wheat Is planted and the response is the yield per parcel (in grams). A CRD has ended in the rejection of the null hypothesis. So, now he should study a total of _ _ comparisons of treatment means. In a CRD with 4 treatments the alternative hypothesis is The fundamental assumption in the analysis of variance is that the response variable is normally distributed for every treatment with variance (same for every treatment) sigma^2. The term _ is the estimator of that common variance. (SST, d.f., F, MSE) In Chapter 9 you studied the t-test for matched pairs (Or "dependent samples"). A matched pair design is a particular case of _ _ (CRD, RBD, 2-factorial design) The F distribution is not symmetric: it is skewed to _ The right tail 1% critical F-value for 10 d.f. in the numerator and 18 d.f. in the denominator Is _ A (n). __ is the object or subject on which the response variable is measured.
