Answer:
Standard errors are 0.049, 0.035, 0.022, and 0.016.
Step-by-step explanation:
The given value of population proportion (P) = 0.56
Given sample sizes (n ) 100, 200, 500, and 1000.
Now standard error is required to calculate.
Use the below formula to find standard error.
When sample size is n = 100
When sample size is n = 200
When sample size is n = 500
When sample size is n = 1000
Answer:
cup of blueberries
Step-by-step explanation:
Since David starts out with 3 1/2 cups of blueberries and uses 1/4 cup to make a smoothie, we will need to subtract 1/4 from his starting amount of 3 1/2
David now has 3 1/4 cup of blueberries
David then uses half of this new amount of blueberries to make his pancakes. We will need to divide by 2 in order to figure out how much half is
- First we can turn 3 1/4 into an improper fraction to make it easier to work with → 3 1/4 = 13/4
- Now dividing 13/4 by 2 gives us
- David used 13/8 cups of blueberries to make his pancakes
- Turning this back into a mixed number leaves him with 1 5/8 cup of blueberries
Answer:
E. a contingency table
Step-by-step explanation:
First we need to identify the number of variables in the survey. The choice of graphical display depends on the number of variables and their types.
The survey was conducted to study the relationship between:
1) Whether the family is buying or renting their homes
This is a categorical variable with 2 possible options
2) Marital Status of the Parents
This is also a categorical variable with 4 possible options: Married, single, divorced, and widowed
This means, we have to display 2 categorical variables side by side, showing their relationship. To display such data we always use a contingency table.
A contingency table or a 2-way table is a type of Frequency Distribution that is used to summarize the relationship between two or more Categorical Variables. Its similar to matrix form i.e. in form of rows and columns of a table. The minimum size is 2 rows and 2 columns.
An example of the contingency table that can be drawn for a data collected in a similar survey is shown in the image below.
