Answer:
A. 71% (±18%)
Step-by-step explanation:
Based on the confidence interval relation :
Mean ± Margin of error
The mean could be any given value :
However, the margin of error at a given confis nce level will will affected by the sample size, larger sample sizes will result in smaller margin of error values as the it will result in a large value denominator hence giving a small margin if error value when divided.
Margin of Error = Zcritical * σ/√n
Since.weve been told that the sample size is small, this will result in a large error margin value, from the options given, the value with the largest error margin value will be produced by the smallest samole size. Hence the option with the largest error margin value is ; ±18%
Answer:
Zero
Step-by-step explanation:
Maybe something like:
200s + 105a + 200 = 1,000
You can use x and y instead of s for student and a for adult.
Are the adults and students charged the same? If so then:
200x + 105x + 200 = 1,000
