- With 95% confidence, calculate the margin of error to estimate the population mean with a simple random sample of 8 items in a sample standard deviation of 3.5.arrow_forwardIf the level of confidence is lowered from 95% to 90 % , but the allowable error and the standard deviation remain the same, what happens to the required sample size?arrow_forwardIf an interval estimate is said to be constructed at the 90% confidence level, the confidence coefficient would be Group of answer choices 0.1 0.05 0.95 0.9arrow_forward
- A sample of 81 observations is taken from a normal population with a standard deviation of 6.The sample mean is 41. Determine the 99% confidence interval for the population mean.arrow_forwardTrue or False? When the population variance is unknown and the size of a random sample is 20, then the student’s t used to construct a 90% confidence interval for the population mean is 1.729, by Appendix D.arrow_forwardCountry Financial, a financial services company, uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time (USA Today, April 4, 2012). In February 2012, a sample of 1000 adults showed 410 indicating that their financial security was more than fair. In February 2010, a sample of 900 adults showed 315 indicating that their financial security was more than fair. State the hypotheses that can be used to test for a significant difference between the population proportions for the two years. What is the sample proportion indicating that their financial security was more than fair in 2012? In 2010? Conduct the hypothesis test and compute the p-value. At a .05 level of significance, what is your conclusion? What is the 95% confidence interval estimate of the difference between the two population proportions?arrow_forward
- The null and alternate hypotheses are: H0 : μ1 = μ2 H1 : μ1 ≠ μ2 A random sample of 8 observations from one population revealed a sample mean of 23 and a sample standard deviation of 4.6. A random sample of 8 observations from another population revealed a sample mean of 27 and a sample standard deviation of 4.6. The population standard deviations are unknown but assumed to be equal. At the 0.01 significance level, is there a difference between the population means? a. State the decision rule. b. Compute the pooled estimate of the population variance. c. Compute the test statistic.arrow_forwardAn estimate of a population parameter that provides an interval of values believed to contain the value of the parameter is known as the Group of answer choices population estimate interval estimate parameter value confidence leveLarrow_forward7 In interval estimation of a population parameter, increasing the sample size would a reduce the margin of sampling error, increasing the confidence level. b reduce the margin of sampling error, making the interval estimate more precise. c reduce the margin of sampling error, diminishing the error probability. d increase the margin of sampling error, making the interval estimate more precise.arrow_forward
- A chemist measures the haptoglobin concentrations (in grams per liter) in the blood of eight healthy adults. The mean and standard deviation of the haptoglobin concentrations (in grams per liter) are 1.615 and 1.387 respectively. Obtain a 90% confidence interval for the mean haptoglobin concentration in adults.arrow_forwardAccording to the Annual survey of drugs expenditure in country X, the annual expenditure for prescription drugs is $838 per person in the Northeast region of the country. A sample of 60 individuals in the Midwest shows a per person expenditure for prescription drugs of $745. Further, it is given that the population standard deviation of $300. Formulate hypotheses for a test to determine whether the sample data support the conclusion that the population annual expenditure for prescription drugs per person is lower in the Midwest than in the Northeast and Identify whether it is a two-tail test or a one tail test (Left or right tail).arrow_forwardWhat is the level of significance for the confidence level 92%?arrow_forward
