Henrietta surveyed her high school classmates on their favorite subjects. She recorded their gender and favorite subject. She concluded that if she surveyed 500 male and 500 female high school students she would find a higher number of males that preferred history than the number of females that preferred math. Was she correct?
Responses
A No, because the relative frequency of males who like history is lower than the relative frequency of females who like math.No, because the relative frequency of males who like history is lower than the relative frequency of females who like math.
B Yes, because the relative frequency of males who like history is lower than the relative frequency of females who like math.Yes, because the relative frequency of males who like history is lower than the relative frequency of females who like math.
C Yes, because 7 males liked history while only 6 females liked math. Therefore, the number of males would be greater.Yes, because 7 males liked history while only 6 females liked math. Therefore, the number of males would be greater.
D No, because the relative frequency of males who like history is higher than the relative frequency of females who like math.

Mr. White collected data from his eighth grade class on whether they prefer the zoo or the museum. Based on the data collected, if the eighth grade has 90 girls and 78 boys, which statement is true?
Responses
A 36 girls will choose the zoo36 girls will choose the zoo
B 47 boys will choose the museum47 boys will choose the museum
C 31 boys will choose the zoo31 boys will choose the zoo
D 60 girls will choose the museum60 girls will choose the museum
E 40 girls will choose the zoo
There is not enough information to determine which statement is true. The question only states that Mr. White collected data on zoo vs museum preferences, but it does not provide any information on the number of students who prefer each option.
To determine which two-way table displays whether or not the students like school and if they have siblings, we need to analyze the given data.
Looking at the survey data, we see that there are three categories for each student: gender, having siblings, and liking school. We want to create a two-way table that cross-tabulates the variables "Have Siblings" and "Like School."
Let's create a table using the information provided:
| Have Siblings | Don't Have Siblings |
------------|---------------|---------------------|
Like School | | |
Don't Like | | |
Now, let's fill in the table using the given data:
| Have Siblings | Don't Have Siblings |
------------|---------------|---------------------|
Like School | 4 | 4 |
Don't Like | 1 | 1 |
By counting the number of students who like school and have siblings and the number of students who don't like school and have siblings, we can complete the table.
Now, let's compare this table to the options provided:
a
12877.png
b
12876.png
c
12875.png
d
12878.png
By comparing the completed table with the options, we can see that option (b) 12876.png displays the correct cross-tabulation of "Like School" and "Have Siblings."
Therefore, the correct answer is option (b) 12876.png.
