Pamela wants to learn more about the career preferences of students in her school. she interviews a number of students from the advanced science classes. why is this sample likely to be biased? 1.advanced science students may not have clear career preferences. 2.the numbers of boys and girls in the advanced science classes are not equal. 3.advanced science students are not representative of all the students in the school. 4.it is too early for students to have career preferences while still in school.

Option 3 is right.

Step-by-step explanation:

Given that Pamela wants to learn more about the career preferences of students in her school. She interviews a number of students from the advanced science classes.

The sample will not be a random sample because only one set of students is interviewed.

option 1 is not right, because it is not about the defects of advanced science students.

Option 2 is not equal because gender equality is not essential.

Option 4 is wrong because when all school students are the population, age is right.

Option 3 is right.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
