Answer (4,5,6) with complete solutions
You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p∗=18%p∗=18%. You would like to be 99.9% confident that your esimate is within 5% of the true population proportion. How large of a sample size is required?n = Do not round mid-calculation. However, use a critical value accurate to three decimal places.
Data from a representative sample were used to estimate that 33% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money. You decide to conduct a survey to estimate this proportion for the current year. What is the required sample size if you want to estimate this proportion with a margin of error of 0.04? Calculate the required sample size first using 0.33 as a preliminary estimate of p. (Round your answer up to the nearest integer.) The sample size of _____ should be used for this study because it will guarantee a margin of error of no greater than 0.04. The other sample size computed will only guarantee a margin of error no greater than 0.04 if p < _____ or if p > ______ .
Use the Student's tt-distribution to find the tt-value for each of the given scenarios. Round tt-values to four decimal places. Find the value of tt such that the area in the right tail of the tt-distribution is 0.0005, if the sample size is 130. t= Find the value of tt such that the area in the left tail of the tt-distribution is 0.01, if the sample size is 123. t= Find the value of tt such that the area in the right tail of the tt-distribution is 0.005, if the sample size is 136. t= Find the two values of tt such that 80% of the area under the tt-distribution is centered around the mean, if the sample size is 96. Enter the solutions using a comma-separated list. t=
You want to obtain a sample to estimate a population proportion. 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
Relative to the population mean, what happens to the possible sample means for samples of the same size as the sample size increases? Explain the relevance of this property in estimating a population mean by a sample mean.
You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p∗=72%p∗=72%. You would like to be 95% confident that your esimate is within 0.2% of the true population proportion. How large of a sample size is required?n = Do not round mid-calculation. However, use a critical value accurate to three decimal places.
Determine 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. Assume the population is normally distributed. n =
you want to obtain a sample to esimate a population proportion. Based on previous evidence, you believe the population standard devition is approximately 65.5. You would like to be 99% confident that your estimate is within 1 of the true population mean. How large of a sample size is required? Do not round mid calculation. Use a critical value rounded to three decimal places.
You want to obtain a sample to estimate a population proportion. 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 1.5% of the true population proportion. How large of a sample size is required? Do not round mid-calculation. n =
