The larger the sample size, the smaller the margin of error.
The margin of error is dependent on the confidence interval.I'll give you examples to understand it better.We know:Confidence Interval (CI) = x(bar) ± margin of error (MOE)MOE = (z confidence)(sigma sub x bar, aka standard error of mean)When CI = 95%, MOE = (1.96)(sigma sub x bar)When CI = 90%, MOE = (1.64)(sigma sub x bar)Naturally, the margin of error will decrease as confidence level decreases.
The margin of error increases as the level of confidence increases because the larger the expected proportion of intervals that will contain the parameter, the larger the margin of error.
Point Estimate of the Mean: The point estimate of the mean is 16, since this is the sample mean. 95% Confidence Interval Estimate for the Mean: The 95% confidence interval estimate for the mean can be calculated using the following formula: Mean +/- Margin of Error = (16 +/- 1.96*(9/sqrt(50))) = 16 +/- 1.51 = 14.49 to 17.51 99% Confidence Interval Estimate for the Mean: The 99% confidence interval estimate for the mean can be calculated using the following formula: Mean +/- Margin of Error = (16 +/- 2.58*(9/sqrt(50))) = 16 +/- 2.13 = 13.87 to 18.13
Margin of safety ratio = margin of safety/sales revenue
Contribution of margin safety x margin of safety
Drugs with a low therapeutic index have a narrow margin of safety.
First you need to find the break even sales. Break even sales = fixed expenses/ CM ratio Break even sales = 3600/.24 = 15,000 Then find the margin of safety dollars. margin of safety dollars = budgeted sales - break even sales margin of satefy dollars = 200,000 - 15,000 = 185,000 Then you can find the margin of safety percent Margin of safety percent = margin of safety dollars/ budgeted sales dollars margin of safey percent = 185,000/200,000 = 92.5%
Margin of safety is the difference between the intrinsic value of a stock and its market price. To have a margin of safety, one must manage one's financial needs thriftily.
total sales - breakeven= marginal of safety
Margin of safety is the difference between the intrinsic value of a stock and its market price. To have a margin of safety, one must manage one's financial needs thriftily.
yes it can be negative.
SSM = LD1/ED99 SSM = Standard Safety Margin LD1 = Lethal dose for 1% ED99 = Effective Dose for 99%

The margin of safety is the dose of a drug that is lethal for 1% of tested animals divided by the dose that produces the maximum effect for 99% of tested animals. The larger this ratio is, the better you toxicology data will (and thus, the safer the drug will be)
