Lilly collects data on a sample of 40 high school students to evaluate whether the proportion of female high school students who take advanced math courses in high school varies depending upon whether they have been raised primarily by their father or by both their mother and their father. Two variables are found below in the data file: math (0 = no advanced math and 1 = some advanced math) and Parent (1= primarily father and 2 = father and mother).

a) Conduct a crosstabs analysis to examine the proportion of female high school students who take advanced math courses is different for different levels of the parent variable.
b) What percent female students took advanced math class
c) What percent of female students did not take advanced math class when females were raised by just their father?

To conduct a crosstabs analysis and answer the given questions, follow these steps:
Step 1: Organize the data
The given data shows two variables: "Parent" and "Math." Create a table to organize the data properly:
Parent | Math
---------|------
1.0 | 0.0
1.0 | 0.0
1.0 | 0.0
...
Step 2: Calculate the proportion of female high school students taking advanced math for different levels of the "Parent" variable (crosstabs analysis)
To analyze the proportion of female high school students who take advanced math courses for different levels of the "Parent" variable, we need to group the data and calculate the percentages.
For this, we will create a contingency table or crosstab between the variables "Parent" and "Math." Here's how the crosstab would look:
| Math=0 | Math=1 | Total
----------|---------|---------|-------
Parent=1 | x1 | x2 | x1 + x2
Parent=2 | y1 | y2 | y1 + y2
Total | x1 + y1 | x2 + y2 | n = x1 + x2 + y1 + y2
In this table, x1 represents the count of females who do not take advanced math courses and have been raised primarily by their father. Similarly, x2 represents the count of females who take advanced math courses and have been raised primarily by their father.
y1 and y2 represent the same for females who have been raised by both their mother and father.
Step 3: Calculate the percentages for each level of the "Parent" variable
Now, let's calculate the percentage of female students who took advanced math courses for different levels of the "Parent" variable.
a) For females raised solely by their father (Parent=1):
- The total count is (x1 + x2).
- Calculate the percentage of females who took advanced math courses: (x2 / (x1 + x2)) * 100%.
b) For females raised by both their mother and father (Parent=2):
- The total count is (y1 + y2).
- Calculate the percentage of females who took advanced math courses: (y2 / (y1 + y2)) * 100%.
Step 4: Calculate the percentage of female students who took the advanced math class overall
To calculate the overall percentage of female students who took the advanced math class, divide the total count of females taking advanced math by the total number of females:
Overall percentage = ((x2 + y2) / n) * 100%
I cannot provide the actual percentages since the data file is not complete. However, you can follow the steps above to calculate the desired percentages based on the available data.
