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
Answer: The correct option is C .The Ratio Test says that the series converges conditionally.
Step-by-step explanation:
Ratio test is used for testing convergence or divergence in series.
Iet consider a positive series
Summation a subscript n. £an
Let £an > 0.
Consider
Lim as n tends to infinity, 'a' subscript n+1 divided by 'a' subscript n = L
If L < 1 the series converges
If L >1 the series diverges
If L= 1 No conclusion.
The correct option is C because the series converges conditionally if L <1
Alright, lets get started.
Mari adds 4 spoons of honey to a pitcher.
Each spoonful holds 5 mL of honey.
So, total ML of honey mari adds = 4 spoon * 5 ML = 20 ML
Answer : 20 mL of honey does Mari have in all.
Hope it will help :)
%change=100(final-initial)/initial,
%change=100(New price-Original price)/Original price
(Original price*%change)/100=New price-Original price
New Price=(Original price*%change+100*Original price)/100
New Price=Original price(100+%change)/100
Since %change is -4%...
New Price=0.96(Original price)
...
Since original price is $45400
New Price=0.96(45400)
New Price=$43584
