exercise 5:

The following data represent the number of times that a sample of residents in nursing homes who were aged 80 or older fell during a 12-month period.

3 3 4 1 1 2 1 1 2 0

4 1 0 3 2 6 1 0 0 1

0 1 1 1 1 1 3 2 1 0

1 3 1 1 0 4 6 9 0 1

Construct a frequency distribution table for this set of data in Stat Crunch, showing the absolute frequencies, relative frequencies, and cumulative relative frequencies. Would it be advantageous to group the data before constructing a frequency distribution? Why or why not?Construct a Summary Statistics table in Stat Crunch to list the n, mean, mode, Skewness and Kurtosis of the data.

• Using information from the frequency distribution in Exercise 5, answer the following:
• What percentage of the nursing home residents had at least 1 fall?
• What number of falls was the most frequent in this sample?
• What number of falls was least frequent in this sample?
• What percentage of residents had 2 or fewer falls?
• Draw a graphic of the frequency distribution of the data in Exercise 5 using Stat Crunch. Copy and Paste your graphic Describe the shape of the frequency distribution in terms of modality and skewness. Is the number of falls normally distributed?
