Question

2. which survey question is unbiased?

a: "Do you think we should allow them to cut down the trees and pave over grass for the new playground?"
b: "Which do you prefer with a meal-water, or a durupy sweet soft drink?"
c: "Should there be a school dress code?"
d: "Do you prefer brining a healthy lunch to school or eating cafeteria food"

Answer 1

thank you so much :)

Answer 2

Do you think we should allow them ... starts out biased (should we throw them in jail or merely hang them?)

"syrupy soft drink" implies bias

---> Should there be a ----- no bias

healthy versus unhealthy ? certainly biased

Answer 3

You're welcome.

Answer 12

A survey showed that 62% of car owners prefer two-door cars, 26% prefer four-door cars, and 12% have no preference. You ask 400 people. How many do you think will prefer the two-door cars?

Answer 13

Tony works in a factory that produces 1,000 computers each day. When 50 computers were sampled, it was found that 7 were defective. Estimate how many defective computers are made each day.

Answer 14

Question 10 of 15
The spinner is divided into equal parts. Use a tree diagram to find the probability that the spinner will land on a consonant both times if the spinner is spun twice.

A circle is divided equally into three sections.

Answer 15

Based on the given survey, 62% of car owners prefer two-door cars. So, out of 400 people, the estimated number of people who prefer two-door cars is:

62% of 400 = (62/100) x 400 = 248

Therefore, it is estimated that 248 people out of 400 will prefer two-door cars.

Answer 16

To estimate the number of defective computers made each day, we can use the method of proportion. We know that 7 computers out of a sample of 50 were defective. So, the proportion of defective computers in the sample is:

7/50 = 0.14

We can assume that the proportion of defective computers in the population of 1,000 computers is the same as the proportion in the sample of 50 computers. Then, the estimated number of defective computers made each day is:

0.14 x 1,000 = 140

Therefore, it is estimated that 140 defective computers are made each day.

Answer 17

Here's the tree diagram to find the probability that the spinner will land on a consonant both times if the spinner is spun twice:

First spin:

- Consonant (C) with probability 2/3
- Vowel (V) with probability 1/3

Second spin for Consonant (C) outcome from the first spin:

- Consonant (C) with probability 2/3
- Vowel (V) with probability 1/3

Second spin for Vowel (V) outcome from the first spin:

- Consonant (C) with probability 2/3
- Vowel (V) with probability 1/3

So, there are four possible outcomes for two spins: CC, CV, VC, and VV.

The probability that the spinner will land on a consonant both times is the probability of outcome CC, which is:

(2/3) x (2/3) = 4/9

Therefore, the probability that the spinner will land on a consonant both times if the spinner is spun twice is 4/9.
