Suppose scores of a standardized test are normally distributed and have a known population standard deviation of 8 points and an unknown population mean. A random sample of 25 scores is taken and gives a sample mean of 93 points. Find the margin of error for a confidence interval for the population mean with a 98% confidence level. z0.10 z0.05 z0.025 z0.01 z0.005 1.282 1.645 1.960 2.326 2.576 You may use a calculator or the common z values above. Round...
Use the same sample of 51 boys in problem. The standard deviation of daily iron intake in the larger population of 9 to 11-year-old boys was 5.56mg. a. We wish to test if the standard deviation from the low-income group is lower than that of the general population. Use -0.10. : H: ii. Summary Sample Statistics: iii. Significance level: iv. p-value: v. Conclusion: vi. Is the standard deviation of iron intake among the low-income group lower than that of the...
In constructing a 90% confidence level estimate of the mean when the population standard deviation (σ) is known what will be your z score used in the formula? HINT: Be sure to review page 236 "Finding Z scores from Known Areas - Special Cases" and Tabel A-2. If you identified it as 1.64 contact me in the DB and I will provide partial credit. Please see my lecture "CIE of the mean z and t examples 2015" as to an...
