1. use a random number generator to randomly select four samples from the population. This time. make the samples of size n 10. Record the samples in Table 76e . As before. for each sample. calculate the mean to the nearest tenth. Record them the spaces provided. Record the sample means for the rest Of the class. Sample 1 Sample 2 Sample 3 Sample 4 Sample means from other groups Means: Table7.6 2. Calculate the following: 3. For the original population. construct a histogram. Make intervals with a bar width Of one day. Sketch the graph using a ruler and pencil. Scale the axes. Figure 7.13 a. Draw a smooth Curve through the tops Of the bars Of the histogram. Use one to two complete sentences to describe the general shape Of the curve. Sample Sample Sample Sample Sample means from Other groups Means: Table 7.6
