COMPUTE THE FOLLOWING

COMPUTE FOR THE FOLLOWING: 1. Estimate the mean weight of 6 students randomly chosen in a university if student 1 weighs 53 kg; student 2 weighs 64 kg; student 3 weighs 49 kg; student 4 weighs 59 kg; student 5 weighs 62 kg and student 6 weighs 55 kg. ANSWER: 2. A random sample is drawn from a population of known standard deviation 11.3 . Construct a 90% confidence interval for the population mean based on the information given: n = 36 X=102.2 n = 100 X=105.2 3. A random sample is drawn from population of unknown deviation. Construct a 99% confidence interval for the population mean based on the information given: n = 49 X=17.1 0 =2.1 n = 169 X=17.1 0 =2.1 4. A random sample of size 144 is drawn from a population whose distribution, mean, and standard deviation are all unknown. The summary statistics are x= 58.2 and o = 2.6 . Construct a 90% confidence interval for the population mean u
