Need on last one 30 points mrs. jones teaches an 8th grade math class in texas. she wants to find out if 8th graders in texas prefer cola or juice, so she polls her thirty 8th grade students. she finds out the most of them prefer cola over juice. identify the population, sample, what method of sampling mrs. jones used, and if there was any bias in the sample.

Population = all Texas 8th graders
Sample = Mrs. Jones's thirty 8th graders
Sampling method = convenience sampling

Yes, there was a sampling bias. Since the complete sample was from the same school and class, it does not represent the total population of Texas 8th graders very well.

Hoped this helped :D

step-by-step explanation:

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
