You want to know the number of students in your school that have a January birthday. You survey the students in your math class. Three students have a January birthday, and 32 do not. So, you conclude that about 8.6% of the students in your school have a January birthday. Determine whether the conclusion is valid. Explain.

my answer: the conclusion is not valid-it's biased because only students in math class were surveyed and that doesn't really serve as a fair representation for the entire school.

Your answer is correct. The conclusion is not valid because the survey was conducted only among the students in your math class. This cannot be considered as a fair representation of the entire school. The data collected is limited and biased towards the students in the math class. To make a valid conclusion, a larger and more diverse sample of students from different classes or grades should be surveyed. This would help ensure a more accurate representation of the entire school population.

Your answer is correct. The conclusion is not valid because the survey was conducted only among the students in your math class. This limits the sample size and restricts the data to a specific group of students, which may not be representative of the entire school.

To determine the number of students in the school with a January birthday, you would need to conduct a more comprehensive survey that includes students from different classes, grade levels, and possibly even teachers or staff members. This would provide a larger and more diverse sample size, improving the accuracy and reliability of the results.

Without surveying a broader range of students, it is not appropriate to generalize the findings from your math class to the entire school population. This is because different classes or groups of students may have different distributions of birthdays, resulting in potential bias in the conclusions drawn.

why would the math class have students whose birthdays are skewed?
