Step 1
The sample size can be calculated as:
Here,
z = desired confidence level
E = The allowable margin of error ( sampling error)
σ = Population standard deviation
At a 95% confidence level, the z value is 1.96 which can be obtained by using the standard normal table.
Given:
z = 1.96 = The value at 95% confidence level
E = 1
σ = 16.6
Substitute the given values in the above-mentioned formula as follows:

At this point in time, you have no reasonable preliminary estimation for the population proportion. You would like to be 90% confident that you estimate is within 2% of the true population proportion. How large of a sample size is required? Hint: Video [+] n = Submit Question 近arrow_forward
- A population of values has a normal distribution with 45.2 and a 67.7. You intend to draw a random sample of size n = 108. Please answer the following questions, and show your answers to 1 decimal place. Find the value separating the bottom 35% values from the top 65% values. Find the sample mean separating the bottpm 35% sample means from the top 65% sample means.arrow_forwardThe finite population correction is most useful for which of the following? a. It adjusts the estimated mean when the sample size is a large fraction of the population size. b. It adjusts the standard error of the mean when the sample size is a small fraction of the population size. c. It adjusts the estimated mean when the sample size is a small fraction of the population size. d. It adjusts the standard error of the mean when the sample size is a large fraction of the population size.arrow_forwardDetermine the minimum sample size required when you want to be 95% confident that the sample mean is within two units of the population mean and = 4.3.
