Question

What you have Distribution of X. Find the mean and standard deviation of Sampling Distribution. To do this, click on: c STAT → BASIC STATISTICS → DISPLAY DESCRIPT STATISTICS On the input screen that appears, select C3 for the Variable. The results will be in the Session Window. Wait until after to print the Session Window.) a. How does the mean of C3 (x) compare to the mean of the original population, μ? Recall that the mean of the original population is 100. Note:g should be approximately equal to u). If so, the results of your simulation of a sampling distribution confirm that: ug should be Are the two values close? approximately equal to u. b. How does ơe, the standard deviation of C3, compare to the standard deviation of the original population, ơ? Note: ơr should be approx. equal to ơ Nn). For this example, n 2 and ơ- 10 Using your calculator, calculate ơAn Compare your calculation to the standard deviation of C3. Are the two numbers close? your simulation of a sampling distribution confirm that σ , should be approx. equal to ơ /vn . If so, the results of c. Now compare the shape of a set of data from the original population, C1, with the shape of the sampling distribution, C First, in the Worksheet, give C1 the name: "Population Data". Give C3 the name: "Sample Means n 2). Next, click on: GRAPH HISTOGRAM. Click on the SIMPLE histogram icon. Select both C1 and C3 for the GRAPH VARIABLES. If you thet click on the button labeled MULTIPLE GRAPHS, you can SAME Y and also SAME X, including bins by clicking on the
