Assume a population of 1, 3, and 8. Assume that samples of size n = 2 are randomly selected with replacement from the population. Listed below are the nine different samples. 1,3 1,8 3,1 3,3 3,8 8,1 8,3 8,8
1. Find the value of the population standard deviation σ.
2. 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.
3. Find the mean of the sampling distribution of the sample standard deviations.
4. Do the sample standard deviations target the value of the population standard deviation? In general, do sample standard deviations make good estimators of population standard deviations? Why or why not?
A. The sample standard deviations do not target the population standard deviation, therefore, sample standard deviations are unbiased estimators.
B. The sample standard deviations do not target the population standard deviation, therefore, sample standard deviations are biased estimators.
C. The sample standard deviations do target the population standard deviation, therefore, sample standard deviations are based estimators.
D. The sample standard deviations do target the population standard deviation, therefore, sample standard deviations are unbiased estimators.

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
