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
Point B is located at (0, -3). When both x and y coordinates are positive,
it lies in the first quadrant. If both are negative, it lies in the third
quadrant. If x is negative and y is positive, it is in the second quadrant. If x
is positive and y is negative, it is in the fourth quadrant.

Answer:
Original Value= $361.21
Step-by-step explanation:
Giving the following information:
The value of the savings bond increases by 3% each year. One year after it was purchased, the value of the savings bond was $515.
<u>To calculate the original value of the bond, we need to use the following formula:</u>
OV= PV/(1+i)^n
OV= original value
PV= present value
i= increase rate
n= number of months
OV= 515 / (1,03^12)
OV= $361.21
