You intend to conduct an ANOVA with 4 groups in which each group
will have the same number of subjects: n=16n=16. (This is referred
to as a "balanced" single-factor ANOVA.)
What are the degrees of freedom for the numerator?
d.f.(treatment) =
What are the degrees of freedom for the denominator?
d.f.(error) =
degrees of freedom for the numerator =Number of groups (k)-1 =4-1 =3
degrees of freedom for the denominator =nk-n =16*4-4=60

Analysis of variance compares the means of a response variable for several groups. ANOVA compares the variation within each group to the variation of the mean of each group. The ratio of these two is the F statistic from an F distribution with (number of groups - 1) as the numerator degrees of freedom and (number of observations - number of groups) as the denominator degrees of freedom. You intend to conduct an ANOVA with 4 groups in which each...

You intend to conduct an ANOVA with 42 subjects, which will be divided into 7 treatment groups. What are the degrees of freedom for the numerator? d.f.(treatment) = What are the degrees of freedom for the denominator? d.f.(error) =
You intend to conduct a goodness-of-fit test for a multinomial distribution with 4 categories. You collect data from 87 subjects. What are the degrees of freedom for the χ2χ2 distribution for this test? d.f. =
You intend to conduct a test of independence for a contingency table with 8 categories in the column variable and 2 categories in the row variable. You collect data from 349 subjects. What are the degrees of freedom for the ? 2 distribution for this test? d.f. =
a.) given the following table for a one-way ANOVA test for four treatment groups with six subjects in each group, what would the decision about H0 be if ? H0 is ___ @ P ___ Source Sum of Squares Degrees of Freedom Mean Squares F Ratio P Value Treatment 33 Error Total 145 a-0.05
11. What is the null hypothesis for a t-test for two independent groups? a. If mul and mu2 are the population means of the two groups, then the null hypothesis is Ho: mul-mu2=0. b. If sl and s2 are the population standard deviations of the two groups, then the null hypothesis is Ho: sl-s2=0. 12. Differentiate between a data set that should be analyzed using a paired t-test from a data set that should be analyzed using a t-test for...
You intend to conduct a goodness-of-fit test for a multinomial distribution with 4 categories. You collect data from 63 subjects. What are the degrees of freedom for the χ 2 distribution for this test?
11.2 You intend to conduct a goodness-of-fit test for a multinomial distribution with 7 categories. You collect data from 74 subjects. What are the degrees of freedom for the x2 distribution for this test? d.f. = Submit License Question 1. Points possible: 1 Unlimited attempts. You are conducting a multinomial Chi-Square Goodness of Fit hypothesis test for the claim that the 4 categories occur with the following frequencies: Ho:PA = 0.2; PB = 0.3; pc = 0.3; PD = 0.2...
