Chapter 7 Worksheet Name:_____________________________
\nGo to StatCrunch and select the applet \u201cSampling Distributions.\u201d In the options choose a bell shape with mean
\n25 and std. dev. 5. Note that the default setting for the calculated statistic is the mean. Click Compute.
\n1. With sample size set to 2, click \u201c1 time,\u201d \u201c5 times,\u201d and \u201c1000 times.\u201d (Hint: click \u201cReset\u201d between
\neach click. Fill in the chart below for the \u201cSample means.\u201d
\n*Note: This applet finds the means of each sample of size 2. \u201c1 time\u201d refers to taking one sample of size 2 and
\nthen finding the mean. \u201c5 times\u201d refers to taking 5 different samples, each of size 2. \u201c1000 times\u201d refers to
\ntaking 1000 different samples, each of size 2.

\nCompare the resulting sampling distribution for \u201c1000 times\u201d to the population (copied below) in terms of
\nshape, center, and spread.

\n2. With sample size set to 5, click \u201c1 time,\u201d \u201c5 times,\u201d and \u201c1000 times.\u201d Describe the resulting sampling
\ndistribution. How does it compare to the original population distribution?
\n*Note: This applet finds the means of each sample of size 5. \u201c1 time\u201d refers to taking one sample of size 5 and
\nthen finding the mean. \u201c5 times\u201d refers to taking 5 different samples, each of size 5. \u201c1000 times\u201d refers to
\ntaking 1000 different samples, each of size 5.

\nCompare the resulting sampling distribution for \u201c1000 times\u201d to the distribution of the population (copied
\nbelow) in terms of shape, center, and spread.

\n3. With sample size set to 25, click \u201c1 time,\u201d \u201c5 times,\u201d and \u201c1000 times.\u201d
\n*Note: This applet finds the means of each sample of size 25. \u201c1 time\u201d refers to taking one sample of size 25
\nand then finding the mean. \u201c5 times\u201d refers to taking 5 different samples, each of size 25. \u201c1000 times\u201d refers
\nto taking 1000 different samples, each of size 25.

\nCompare the resulting sampling distribution for \u201c1000 times\u201d to the distribution of the population (copied
\nbelow) in terms of shape, center, and spread.

\n4. For #1-3, how do the three sampling distributions for \u201c1000 times\u201d compare to each other? What did
\nyou notice happening as the sample size was increased? What do you think will happen if we make the
\nsample size 500?

\n7. What effect did the starting shape of the population distribution have on the shape of the resulting sampling
\ndistribution (compare for all three: \u201c1 time\u201d, \u201c5 times\u201d and \u201c1000 times\u201d)? What happened to the shape of the
\nsampling distributions as the sample size increased and as the number of samples increased?

\n8. Go back to starting with a Normal distribution (25,5). This time change the statistic (near the bottom) to
\nbe standard deviation instead of mean.
\na. With sample size set to 2, click \u201c1 time,\u201d \u201c5 times,\u201d and \u201c1000 times.\u201d Describe the resulting sampling
\ndistributions in terms of shape, center, and spread. Did you notice any patterns or relationship between
\nthe mean (mean of the standard deviations of the samples) and the standard deviation (standard
\ndeviation of the standard deviations of the samples)?
