Suppose you have the following data, with a mean and standard deviation of 5 and 2.1 3 3 4 5 7 8 If you were to subtract 2 from every observation, what change - if any- would you see in the transformed mean and standard deviation? the mean and standard deviation would decrease the mean wold stay the same but the standard deviation would decrease the mean and standard deviation would stay the same the mean would decrease but the...

1. Explain the relationship between sample size and standard error. 2. You have a normal population with a u = 50 and o = 9. You obtain all possible random samples, each with n = 30, from this population and calculate each sample's mean. What will the average value of all the sample means be? a) 50 b) 5.56 c) 30.49 d) Cannot tell without more information 3. You are sampling from a distribution of scores that is positively skewed....

For confidence interval computations, if the sample size is increased, we expect the margin of error to: a. Increase b. Decrease c. stay the same The company you work for produces automotive parts for GM. A certain machine that makes a cutout in a piece of steel averages a cut size of 203.2085 mm with a standard deviation of 0.2083 mm. A random sample of 66 is taken from the population. What is the distribution of the sample mean? Approximately...

Select the FALSE statement regarding the relationship between sampling error and sample size. a.) In order to decrease sampling error, you must increase the sample size. b.) The larger a sample size, the more accurate an estimate can be c.) The standard error increases as the sample size increases. d.) The sample size can impact the sampling error

Question 7 5 pts This is a stand-alone question The value for the standard error of the mean requires that the observations in your sample are independent of each other. Explain what will happen to the standard error of the mean if the observations have a positive covariance. Will the standard error increase, decrease, or stay the same? Justify your answer using the properties of the variance as a linear operator. Give your response in the textbox below. HTML Editora...

Discuss the meaning of the standard error of the estimate. As you collect more data, do you expect that this standard error will increase, decrease, or stay about the same? Explain how you came to this conclusion.
