If a 99% confidence interval is constructed instead of a 95% confidence interval for the population mean, then <u>C. the resulting margin of error will increase and the risk of reporting an incorrect interval will decrease</u>.
<u>Step-by-step explanation</u>:
The margin of error helps in mentioning the amount of random sampling error that occurred in a survey. Increase in the margin of error, makes the result less confidence. So the margin of error of the survey should be less.
The margin of error can be calculated in two different ways:
One is using the standard deviation of population,
Margin of error = Critical value x Standard deviation for the population
Other is using standard error of sample,
Margin of error = Critical value x Standard error of the sample
Answer:
2a/b1 +b2=h
And
2a/h -b2=b1
Step-by-step explanation:
2x is not a way to express this. You could use 2 + x or x +2. But 2x is x multiplied by 2. x + 2 is x plus 2.
