OOOOO}:l> is drawn from ais calculated from the data and used to estimate the Statistic, sample, parameter, populationPopulation, sample, statistic, parameterPopulation, sample, parameter, statisticSample, population, parameter statistic Sample, population, statistic, parameter If the population distribution of scores (X) is normally distributed, then the sampling distribution of)? (assuming the sample is randomly selected) will be: 0 OOO normally distributed only if n is large. normally distributed for any sample size.normally distributed only ifX is large. none of the above. The Central Limit Theorem states that: O OOOO The distribution of the sample mean ()7) is centered at u. The sample mean (X) is approximately normally distributed for large n. The X distribution is approximately normally distributed for large n. The sample standard deviation (S) is approximately normally distributed for large 11. None of the above. The breaking strength (in kg/mm) for a certain type of fabric has mean 1.86 and standard deviation 0.27. A random sample of 80 pieces of fabric is drawn. a. b. C. (4pts) What is the probability that the sample mean breaking strength is less than 1.8 kg/mm? {4pts) Find the 80th percentile of the sample mean breaking strength? (4pts) How large a sample size is needed so that the probability is 0.01 that the sample mean is less than 1.8?Round up to a whole number.
