10.It is desired to test Ho: u = 18 against Ha: u > 18 using data from a random sample of size n=9 taken from a normal distribution with o-4.5. If the rejection region used is X> 21, determine: (a) the probability of type I error (a) (3 marks) (b) the probability of type II error (B) when u = 22 (4 marks) (c) Without calculations can you say whether B(21.5) will be bigger or less than B(22)? Why? (2 marks)

5. Certified Reference Materials (CRM) are prepared in ISO17025 accredited laboratories and sold for the purpose of device calibration. Under some standards the ISO17025 labs must measure their CRM product using two different assay methods that must agree with each other to within some specified amount. The Excel data file contains the assay results from two such methods. a. Perform the two-sample t test for Hoμ₁ =μ2 versus H₁ μ₁ μ2. 10ppm b. Perform a two-sample equivalence test of Ho |Aμ| > 6 versus Ho|Aµ| < d using 6 = and show the equivalence test plot. In the Options submeu choose the (1 - 2α) confidence interval method. c. Explain how the two tests are different from each other.

Use the bootstrap distributions in Figure 1 to estimate the value of the sample statistic and standard error, and then use this information to give a 95 % confidence interval. In addition, give notation for the parameter being estimated. The bootstrap distribution in Figure 1, generated for a sample correlation to 0.25 0.30 0.35 0.40 0.45 0.50 0.55 Figure 1 Bootstrap distribution (a) Give the sample statistic for the parameter being estimated. Round your answer to one decimal place. Sample statistic = eTextbook and Media (b) Estimate the standard error. Round your answer to two decimal places. standard error = i eTextbook and Media (c) Give the 95 % confidence interval. Round your answers to two decimal places, if necessary.
