For the following situations, tell what testing distribution you should use. (normal distribution, t-distribution, chi-square or ANOVA). a. A simple random sample of adults is obtained and the sample mean red blood cell count is measured. Assuming we know the population standard deviation, test the claim that the sample is from a population with a mean less than 5.4 cells/mL. b. A study of the flammability of children’s sleepwear across five different laboratories was done. Test the claim that the...

Imagine that you wish to compare a sample mean to a population mean to decide if you can reject the hypothesis that µ1= µ2. Assume that you have the following information: N = 45, M = 10, σ (sigma) = 2, µ = µM= 8. Which of the following types of tests should you use? Group of answer choices A) A z test B) A one-sample t test C)A paired-samples t test D) An independent-samples t test E) None of...

Use the standard normal distribution or the t-distribution to construct a 90% confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why. Interpret the results. In a random sample of 13 people, the mean length of stay at a hospital was 6.9 days. Assume the population standard deviation is 2.1 days and the lengths of stay are normally distributed. Which distribution should be used to construct the confidence interval? A. Use a normal...
