Answer 1

Carla wants to know how many students in her school enjoy watching reality TV shows. She asks all 22 students in her science class and finds that 40% of her classmates enjoy watching reality TV shows. She claims that 40% of the school's student population would be expected to enjoy watching reality TV shows. Is Carla making a valid inference about her population?

Answer 2

A)No, it is not a valid inference because her classmates do not make up a random sample of the students in the school
B)No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample of the students in her school
C) Yes, it is a valid inference because she asked all 22 students in her science class
D)Yes, it is a valid inference because her classmates make up a random sample of the students in the school

@Maliboo

Answer 4

what do you think?

Answer 5

I think its c but last time I put that it said I was wrong

Answer 6

it's not C

Answer 7

I know its yes so it has to be d

Answer 8

it says she wants to find out how many students in her school enjoy watching reality shows but she only asks 22

Answer 9

wouldn't her science class be at school

Answer 10

it can't be D because she only asks the students in her science class not the whole school

Answer 11

yes but in this its about making infrences based off of a sample

Answer 12

random sample has to be from the whole thing
choosing all the students from her science class isn't random

Answer 13

here is another question from the hw
Angela wants to know how many families in her neighborhood plan to attend the parade. She puts all 120 of the neighborhood addresses in a hat and draws a random sample of 30 addresses. She then asks those families if they plan to attend the parade. She finds that 40% of the families plan to attend the parade. She claims that 40% of the neighborhood families would be expected to attend the parade. Is this a valid inference?

Answer 14

that would be a valid reference

Answer 15

this one I got correct when I chose
Yes, this is a valid inference because she took a random sample of the neighborhood

Answer 16

since she did the whole neighborhood not a specific section

Answer 17

so since in the one above its from a specific section it can,t be valid

Answer 18

correct it can't be valid

Answer 19

so it would be b
