Assume that samples of size n-2 are randomly selected with replacement from the population, Listed below are the nine dferent samples. Complete parts a through d below of 1 11,11 11,4 3,11 4,3 4.11 11,3 3,3 3,4 4,4 of 1 a. Find the value of the population standard deviation σ. о» of 1 Round to three decimal places as needed.) b. Find the standard deviation of each of the nine samples, then summarize the sampling distribution of the standard deviations in the format of a table representing the probability distribution of the distinct standard deviation values. Use ascending order of the sample standard deviations Probability of 1 0 of 1 Type integers or fractions.) 1 of 1 e. Find the mean of the sampling distribution of the sample standard deviations The mean of the sampling distribution of the sample standard deviations is 1 of 2 (Round to three decimal places as needed ) deviation?
