3,500 women between the ages 60 -74 years are in a town consisting of a population of 15,000 persons. 85 cases of cancer are in the town one year and 30 of these cases were women 60 -74 years old. What is the prevalence of cancer among women of this age group?
Solutions
Expert Solution
There are 15000 population of a town consisting of 3,500 women between ages 60-74 years.
Total cases of cancer in one year = 85.
Total cases of cancer for women for 60-74 years of age = 30.
Prevalance is basically a rate or is reffered to as prevalance rate is the proportion of persons in a population who have particular disease. It can be expressed in terms of percentage or it can be considered in terms of rate
For calculating the prevalance we have to calculate the probability of a person suffering from disease.
Therefore the prevalance of women of age group 60-74 for cancer is 0.008571. It can also be expressed in terms of percentage given by
Therefore the prevalance is that 0.85% of the population is affected or we can say that out of 15,000 persons , we have prevalnce as
It indicates that out of 15000 persons 128.5~129 women of age group 60-74 suffer from cancer

women between the ages of 70 and 80 were randomly selected from
the general population of women in this age group to take part in a
special program to decrease reaction time (speed). After the
course, the women had an average reaction time of 1.7 seconds.
Assume that the mean reaction time for the general population of
women in this age group is 1.9, with a standard deviation of 0.6
seconds. (Assume that the population is approximately normal.)

In a population of 158 people: 85 men and 73 women, it was found
that 60 men and 46 women had health insurance, the rest no. 40 of
the men with health insurance and 9 of the men without insurance,
visited the MD office more than 5 times last year. In the other
hand, 35 of the women with insurance and 8 of the women without
insurance, visited the MD office more than 5 times last year.

Questions A - F
A recent survey of 1000 American women between the ages of 45
and 64 asked them what medical condition they most feared. Of those
sampled 61% said breast cancer, 8% said heart disease, and the rest
picked other conditions. By contrast, currently about 3% of female
deaths are due to breast cancer, whereas 32% are due to heart
disease.
A. Construct a 95% confidence interval for the population
proportion of women who most feared breast cancer....

A certain group of symptom-free women between the ages of 40 and
50 are randomly selected to participate in mammography screening.
The incidence rate of breast cancer among such women is 0.8%. The
false negative rate for the mammogram is 10%. The false positive
rate is 7%. If a the mammogram results for a particular woman are
positive (indicating that she has breast cancer), what is the
probability that she actually has breast cancer?
