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?
Margin of safety ratio = margin of safety/sales revenue
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%
What is a margin of safety as well as how it can help minimize risk. Use examples in your explanation.?
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.
How do you calculate the margin of safety?
total sales - breakeven= marginal of safety

Can the margin of safety ever be negative?
yes it can be negative.
Standard margin of safety in pharmacy?
SSM = LD1/ED99 SSM = Standard Safety Margin LD1 = Lethal dose for 1% ED99 = Effective Dose for 99%
What are the release dates for Suspense - 1949 Margin for Safety 3-27?
Suspense - 1949 Margin for Safety 3-27 was released on: USA: 27 February 1951
What is the margin of safety in LD50 200mg and ED50 60mg?
3.333
What is the margin of safety LD50 ED50?
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)
