Do one of the foliowing, as appropriate: (a) Find the critical value 2,112, (b) find the critical value tan, (6) state that neither the normal nor that distribution applies. 13) 90%; n: 10; 0 is unknown; population appears to be normally distributed. 13) A) 2312: 2. 262 . B) twig: 1 812 0) tag: 1.833 D) 1M2 = 1.383 Assume that a sample is used to estimate a population mean p. Use the given confidence level and sample data to find the margin of error. Assume that the sample is a simple random sample and the population has a normal distribution. Round your answer to one more decimal place than the sample standard deviation. 14) 95% confidence; n = 12; i: 31.8; s = 9.4 14) ., a) 5.37 _ e) 5.97 ' c) 7.15 o) 4.48 _
