The difference between 6%, 9%, and 12% Hydrogen Peroxide solution is the Hydrogen content.
The formula for margin of error is (Z*)*(Standard Deviation))/(sqrt(N)), so as N increases, the margin of error decreases. Here N went from 100 to 5000, so N has increased by 4900. This means the margin of error decreases. Since the confidence interval is the mean plus or minus the margin of error, a smaller margin of error means that the confidence interval is narrower.
Presumably, 0.6 percent.
percent includes all answers, whereas valid percent excludes missing answers of I don't know or blanks
No, it is not. A 99% confidence interval would be wider. Best regards, NS
The Z-value for a one-sided 91% confidence interval is 1.34
decrease
There is a 95% probability that the true population proportion lies within the confidence interval.
For a two-tailed interval, they are -1.645 to 1.645
Never!
Confidence interval considers the entire data series to fix the band width with mean and standard deviation considers the present data where as prediction interval is for independent value and for future values.

it would be with a level of significance of 0.15.
Increase your percent confidence to provide an increased width.
