dezoksy [38]

Answer:

Step-by-step explanation:

Given that:

Starting count = 10

Additional count = 3

Starting count + (additional count * number of days)

Exactly on the 3rd week = on the 15th day

10 + (3 * 15)

10 + 45

In a two-way analysis of variance, a main effect is defined as: Select one: a. the mean differences among the levels of one fact
Irina-Kira [14]

Answer:

a. the mean differences among the levels of one factor

Step-by-step explanation:

In statistics, a two-way analysis of variance (ANOVA), a main effect is defined as the mean differences among the levels of one factor.

The aim of a two-way analysis of variance (ANOVA) is to give the relationship or identify if there is an interaction between the two independent variables on the dependent variable.

A large department store examined a sample of 18 credit card sales and recorded the amounts charged for each of three types of c
Leokris [45]

Answer:

d. 2 in the numerator, 15 in the denominator

Step-by-step explanation:

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".  

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"  

If we assume that we have 3 groups and on each group from j=1,\dots,n_j we have n_j individuals on each group we can define the following formulas of variation:  

SS_{total}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2  

SS_{between}=SS_{model}=\sum_{j=1}^p n_j (\bar x_{j}-\bar x)^2  

SS_{within}=SS_{error}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2  

We want to test this hypothesis:

\mu_{Master card}=\mu_{Visa}=\mu_{Discover}

And we have this property  

SST=SS_{between}+SS_{within}  

The degrees of freedom for the numerator on this case is given by df_{num}=df_{within}=k-1=3-1=2 where k =3 represent the number of groups.

The degrees of freedom for the denominator on this case is given by df_{den}=df_{between}=N-K=18-3=15.

And the total degrees of freedom would be df=N-1=18 -1 =17

On this case the correct answer would be 2 for the numerator and 15 for the denominator.  

d. 2 in the numerator, 15 in the denominator
