- Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 21, upper bound is 29. The point estimate of the population mean is nothing.arrow_forwardA confidence interval for a mean is (-11, 10). This interval would be wider if The sample mean was larger or the variability of the data was larger. The investigator wanted to be more confident of their results, or there was more information. The variability of the data was small, or the sample mean was larger. The variability of the data was larger, or the investigator wanted to be more confident. None of the above.arrow_forwardOne year, the mean age of an inmate on death row was 38.3 years. A sociologist wondered whether the mean age of a death-row inmate has changed since then. She randomly selects 32 death-row inmates and finds that their mean age is 37.3, with a standard deviation of 8.7. Construct a 95% confidence interval about the mean age. What does the interval imply? E Click the icon to view the table of critical t-values. Choose the correct hypotheses. H, Hi: (Type integers or decimals. Do not round.) Construct a 95% confidence interval about the mean age. With 95% confidence, the mean age of a death row inmate is between places as needed.) What does the interval imply?arrow_forward
- If n = 120 and X = 96, construct a 90% confidence interval for the population proportion, p. Give your answers to three decimals < p <arrow_forwardHeights for teenage boys and girls were calculated. The mean height for the sample of 47 boys was 185 cm and the variance was 58. For the sample of 66 girls, the mean was 174 cm and the variance was 69. There is no reason to assume the variances would be equal. Estimate how much taller teenage boys are using a 87% confidence level. Express this in the (point estimate) ± (margin of error) format. Round answers to 2 decimal places. Harrow_forwardwe want to obtain a sample to estimate a population mean. Based on previous evidence, researchers believe the population standard deviation is approximately 38.7. We would like to be 99% confident that the estimate is within 4 of the true population mean. How large of a sample size is required ?arrow_forward
- please solve for the followingarrow_forwardTina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.arrow_forwardYou are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 70 dates, the mean record high daily temperature in a certain city has a mean of 86.37°F Assume the population standard deviation is 14.38 F The 90% confidence interval is ( I) (Round to two decimal places as needed.) The 95% confidence interval is ( D (Round to two decimal places as needed.) Which interval is wider? Choose the correct answer below. The 90% confidence interval The 95% confidence interval Interpret the results. O A. You can be 90% confident that the population mean record high temperature is between the bounds of the 90% confidence interval, and 95% confident for the G50% intonial Click to select your answer(S). 180min ZoT ooarrow_forward
- A researcher is trying to estimate the population mean (μ) of anxiety based on his sample of n = 16 scores. His sample M = 58 and the s = 5.36. Construct the 95% confidence interval for μ.arrow_forwardIf n = 550 and X = 440, construct a 90% confidence interval for the population proportion, p. Give your answers to three decimals < p <arrow_forwardA researcher wants to make a 95% confidence interval for the population mean. She wants the maximum error of estimate to be within 4.8 of the population mean. The population standard deviation is 18.65. What would be the sample size the yield a maximum error of estimate within 4.8 of the population mean?arrow_forward
