Now, randomly select 4 samples of size n = 10 from the population. Record the samples below. As before, for each mple, calculate the mean to the nearest tenth. Record them in the spaces provided. The sample means for the rest of e class (from last quarter) are below.

For the sample mean from n=10 days averaged together, construct a Histogram of the averages. Draw a smooth curve through the tops of the bars of the histogram above.
1. Now, randomly select 4 samples of sizen= 10 from the population. Record the samples below. As before, for each
sample, calculate the mean to the nearest tenth. Record them in the spaces provided. The sample means for the rest of
the class (from last quarter) are below.

Repeat the Procedure for n 10
3. For the sample of means from n = 10 days averaged together, construct a histogram of the averages. Make
intervals with bar widths = 1/2 day (I suggest same as for n=5, .5 to 1, 1 to 1.5, etc). Sketch the graph using a ruler and
pencil. Scale the axes.
Draw a smooth curve through the tops of the bars of the histogram above. Use 1-2 complete sentences to
describe the general shape of the curve.
