Please try the request again. Can anyone elaborate on how this works? Margin of error = (z*)(standard error) 0.004 = (1.96) sqrt[(0.5)(0.5) / n], now solve for n n = 60024.999, so ALWAYS ROUND UP to make sure the margin of error is This means Multiply 2.262 times 2.3 divided by the square root of 10. this contact form

To calculate a CI for the population mean (average), under these conditions, do the following: Determine the confidence level and degrees of freedom and then find the appropriate t*-value. A Survey Of 865 Voters Multiply t* times s and divide that by the square root of n.

Hence keeping with 95% confidence, you need a wider interval than you would have needed with a larger sample size in order to be 95% confident that the population mean falls Use The Given Degree Of Confidence And Sample Data To Construct A Confidence Interval You can only upload a photo or a video.

A Laboratory Tested Twelve Chicken Eggs After you calculate a confidence interval, make sure you always interpret it in words a non-statistician would understand.

This calculation gives you the margin of error. The t-distribution has a similar shape to the Z-distribution except it's flatter and more spread out. Please try the request again. his comment is here The system returned: (22) Invalid argument The remote host or network may be down.

You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm). When a statistical characteristic that's being measured (such as income, IQ, price, height, quantity, or weight) is numerical, most people want to estimate the mean (average) value for the population. You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM. find the minimum sample size you should use to assure that your estimate of p will be within the required margin of error around the population p.

The formula for a confidence interval for one population mean in this case is is the critical t*-value from the t-distribution with n - 1 degrees of freedom (where n is This t*-value is found by looking at the t-table. Use the given data to find the minimum sample size required to estimate the population proportion.? The system returned: (22) Invalid argument The remote host or network may be down.

Find the sample mean and the sample standard deviation (s) for the sample. Your cache administrator is webmaster. Use the given data to find the minimum sample size required to estimate the population proportion.? Then find the row corresponding to df = 9.

In addition to having a larger critical value (t* versus z*), the smaller sample size increases the margin of error, because n is in its denominator. Browse hundreds of Statistics and Probability tutors. You can only upload videos smaller than 600MB. What is 3/5 of 200?

For small values of n and a specific confidence level, the critical values on the t-distribution are larger than on the Z-distribution, so when you use the critical values from the
