Compute the population mean margin of error for a 90 percent confidence interval when sigma is 4 and the sample size is 36?
1.0966
How does sample size affect the margin of error?
The larger the sample size, the smaller the margin of error.
Why does the margin of error increase as the confidence increases?
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.
Why does margin of error increases while level of confidence increases?
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.
TO ESTIMATE THE AVERAGE AGE OF STUDENTS A SAMPLE OF 50 PARTICIPANTS WAS OBTAINED, WITH A MEAN OF 16 AND A POPULATIONAL VARIATION OF 9, calculate:* POINT ESTIMATE OF THE MEANS* 95% AND 99% CONFIDENCE INTERVAL ESTIMATES FOR THE MEANS?
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
What is margin of safety ratio?

Profit margin formula?
Contribution of margin safety x margin of safety
What does low therapeutic index mean?
Drugs with a low therapeutic index have a narrow margin of safety.
If Hartman Co has fixed costs of 36000 and a contribution margin ration of 24 percent If expected sales are 200000 what is the margin of safety as a percent to sale?
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%
How do you calculate the margin of safety?
total sales - breakeven= marginal of safety

3.333
What is the meaning of safety margin?
Margin of safety is the margin of units of expected sales and break even sales before which company actually start bearing lossformula for margin of safety: actual sales - break even salesFormula for margin of safety ratio : (expected sales - break even sales)/break even salesThe first preventive measures (or) steps taken before an accident (or) incident happens is the margin of safety. The following can be factors that can help increase safety:personal protective gearsemergency equipmentsemergency traininghealth and safety awarenesshealth and safety traininghealth and safety posters/signssafety guidelines complianceAccountingThe margin of safety (in break-even analysis) as regards accounting matters speaks to how much production output or sales levels can fall before a break-even point (BEP) is reached. (At that point profit disappears; it goes to zero.) The margin of safety is calculated like this:Margin of safety = ((Budgeted sales - break-even sales) /Budgeted sales) x 100%FinancialIn finance, the margin of safety is the difference between the intrinsic value of a stock and its current market price.EngineeringThe margin of safety (factor of safety) in engineering is the difference between the strength (of a structure) as designed and built and and the "minimum requirements" (for that structure) under its maximum stress. This "difference" will be expressed as a fraction in most cases, but can be a multiplier in other engineering applications.A link is provided below. The link will provide more information on all these applications of the term. Once you get to the Wikipedia post (to which the link will take you), you can then pick up the link to the specific application you wish to investigate.Margin of safety (financial) in a financial context.
