Question
Construct a 99% confidence interval estimate for the population mean given the following values: 37.3, 15.6 and n-49 a. 32.12 << 42.48 O b. 31.56 << 43.04 O c. 33.63 << 40.97 O d. 32.93 << 41.67 In a sample of 86 people, it is found that 33 of them are married. If we compute the proportion of non-married individuals of this sample, we find that it is: Answer: A random sample of size 49 from normal population yields, mean = 42.4 and standard deviation 19.9. The lower bound of a 99 percent confidence interval for population mean is O a. 36.69 O b. 38.70 O c. 37.63 O d. 34.78
