Ok what is the rest of the question
The answer to this question would have to be D.4
Answer:
Option D
Step-by-step explanation:
Complete question
A student wants to survey the sophomore class of 200 students about whether the school should require uniforms. A random sample of 18 sophomores is surveyed and asked whether they support the school adopting uniforms, and three students said yes. The student wants to construct a 95% confidence interval for the proportion of sophomores who favor the adoption of uniforms. Are the conditions for inference met?
- Yes, the conditions for inference are met.
- No, the 10% condition is not met.
- No, the randomness condition is not met.
- No, the Large Counts Condition is not met.
Solution
10 % of population size of 200 is 20. The sample of 18 is smaller than the 10 % of sample size of 200. As per the 10% rule, the size of sample must be less than 10% of the total size of population. This indicate that the sample is random but its size is less that 30. However, it should be greater that 30. Hence, the large count condition is not met.
Hence, option D is the correct choice of answer
The sales tax was $3.49.
First, you just subtract 69.78 from 100, and you get 30.22. Then you subtract 26.73 from 30.22 and you get 3.49.
Hope that helped!
Since y and y are the same variable then that means that they are the same number. any number subtracted by itself equals zero. The answer is zero and that is ALWAYS zero
