Answer:
The degrees of freedom for the model on this case is given by where k =1 represent the number of variables.
The degrees of freedom for the error on this case is given by . Since we know we can find N.
And the total degrees of freedom would be
Step-by-step explanation:
Previous concepts
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"
When we conduct a multiple regression we want to know about the relationship between several independent or predictor variables and a dependent or criterion variable.
Solution to the problem
If we assume that we have independent variables and we have individuals, we can define the following formulas of variation:
And we have this property
The degrees of freedom for the model on this case is given by where k =1 represent the number of variables.
The degrees of freedom for the error on this case is given by . Since we know we can find N.
And the total degrees of freedom would be
Answer:
1.4
Step-by-step explanation:
We have been given that the number of raisins in a box of a popular cereal is normally distributed, with a mean of 133 raisins per box and a standard deviation of 10 raisins. My cereal box has 147 raisins.
To find the z-score for this box of cereal, we will use z-score formula.
, where,
z = Z-score,
x = Sample score,
= Mean,
= Standard deviation.
Upon substituting our given values, we will get:
Therefore, the z-score for this box of cereal is 1.4.
Answer:
7 songs costs $8.4
Step-by-step explanation:
6/5= $1.2 for each song
1.2 times 7= $8.4
7 songs costs $8.4
