Does it seem to you that people tend to be absent more on some days of the week than on others? Recently, a major biotechnology firm collected data with the hope of determining whether or not its employees were more likely to be absent on some weekdays than on others. The firm examined a random sample of 130 employee absences. The distribution of these 130 absences is shown in the table below. The observed frequency for each category (each weekday) is shown in the first row of numbers. The second row of numbers contains the frequencies expected for a sample of 130 employees if employee absences at the firm are equally likely on each of the five weekdays. The bottom row of numbers contains the following value for each of the categories. (fo-fE)² ƒE (Observed frequency - Expected frequency)² Expected frequency

Dentistry The data in the table below were reported by men in a health follow-up study on the number of teeth lost over a 1-year period (January 1, 1987, to December 31, 1987). (Round your answers to four decimal places.) Number of teeth lost 0 1 2 3 4 5-9 10+ Total Frequency 35,748 1,983 576 136 148 91 138 38,820 You may need to use the appropriate technology to answer this question. (a) If we assume the average number of teeth lost in the 5-9 group is 7 teeth and the average number of teeth lost in the 10+ group is 12 teeth, what is the best estimate of the average number of teeth lost per year? (b) Suppose that on January 1, 1987, a man is 50 years old, that he will live for 30 more years (until 2016), and that the rate of tooth loss over this 30-year period is the same as in 1987. If a man has 13 teeth remaining on January 1, 1987, what is the probability he will need dentures (have 10 or fewer teeth remaining) during his 30-year lifetime? (Hint: Use the Poisson distribution.)
