Answer:
A
Step-by-step explanation:
The fraction for probability is expressed as...
(number of desired outcomes)/(total number of possible outcomes)
Answer:
170
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is of:
Assume:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
What is the smallest sample size required to obtain the desired margin of error?
This is n for which M = 0.03. So
Rounding up, 170.
The problem is saying that 17/20 times the number of dollars equals the number of euros converted. Which in this case to solve your problem, 17/20 times one equals 17/20.
