a)

In the 1999-2000 NHANES report, the reported cancer rate for women subjects age 65 and older is 14%. Using this estimate as the true percentage of all females ages 65and over who have been told by a health care provider that they have cancer, find the probability that if 210 women are selected at random from the population, more than 20% will have been told they have cancer.

b)

In the same report, the cancer rate for men ages 65 and older is 23%. Use this estimate as the percentage of all men ages 65 and older who have been told by a health care provider that they have cancer. Find the probability that among 250 men selected at random that fewer than 20% will have been told they have cancer.

c)

Find the probability that the male cancer rate is at least 3% higher than the female cancer rate in the two samples given above.

An NHANES report gives data for 654 women aged 20 to 29 years. The mean BMI for these 654 women was x = 26.8. On the basis of this sample, we are going to estimate the mean    BMI μ in the population of all 20.6 million women in this age group. We will assume that the NHANES sample is a SRS from a normal distribution with known standard deviation σ = 7.5 Construct three confidence intervals for the mean BMI...

An NHANES report gives data for 654 women aged 20 to 29 years. The mean BMI of these 654 women was 26.8. On the basis of the sample, estimate the mean BMI in the population of all 20.6 million women in the age group. Let us assume that the sample is from a normal population with standard deviation of 7.5. a) Construct a 95% confidence interval for mean BMI of all women b) Construct both a 90% and 99% confidence...

16. An epidemiologic study of breast cancer among elderly women followed 1,000 women, 65-79 years of age, without evidence of breast cancer over several years. Every two years the investigators examined the women for breast cancer. The results were as follows: 12 new cases at the first evaluation, 11 new cases at the second evaluation, 23 new cases at the third evaluation, and 28 new cases at the fourth (and final) evaluation. The investigators also noted that 40 women had...
women who reported an earlier age at menarche were more likely to be heavier at age...
women who reported an earlier age at menarche were more likely to be heavier at age 7 years (average weight = 24.7 kg) compared with those who reported a later age at menarche (average weight = 23.2 kg) (P = 0.01). The correlation between weight at age 7 years and age at menarche was -0.17 (P = 0.009). Q: The -0.17 value is for what? how to find it and why it is important to mention?

Q3: A study followed a population of 2000 women aged over 65 years for 10 years and measured the number of cases of osteoporosis diagnosed during that time period. The investigators were interested in the effect of regular exercise on the development of osteoporosis and divided he women into two groups: 1000 women who took regular exercise and 1000 women who did not take regular exercise. The investigators recorded 800 new cases of osteoporosis over the 10 years of the...

According to a report by the American Cancer Society, more men than women smoke and twice as many smokers die prematurely than nonsmokers. In random samples of 200 males and 200 females, 62 of the males and 54 of the females were smokers. • Is there sufficient evidence to conclude that the proportion of males who smoke is greater than the proportion of females who smoke? α = .01 • Calculate the p-value associated with the test
