Answer:
From the given information we can form the table for a 1000 persons with above 50 years age.
Cancer |
No cancer |
Total |
|
test +ve |
114 |
44 |
158 |
test -ve |
6 |
836 |
842 |
Total |
120 |
880 |
1000 |
The required probability P( cancer/test+ve) = 114/158
=0.721519
Suppose there is a test for prostate cancer for men over 50 that is 95% accurate...
Prostate-specific antigen (PSA) test is a common screening test used for detecting prostate cancer. From Harvard Medical School “Prostate Knowledge” webpage. Is PSA reliable? Although PSA testing can help catch prostate cancer at an early stage, having an elevated PSA (generally considered more than 4 ng/ml) doesn’t necessarily mean that a man has cancer. Noncancerous conditions, including benign prostatic hyperplasia (BPH), or an enlarged prostate, and prostatitis, can raise PSA levels. In fact, studies have shown that about 75% of...
For every 100 men who have PSA blood test: 10 will have an elevated PSA 90 will have a normal PSA Of the 10 with elevatged PSA: 3 are true positive 7 are false negative Of the 90 normal: 1 is false positive 89 are true negative (a)P(cancer)=? (b) How "sensitive" is PSA test? P(+|cancer)=? (c) How "specific" is the PSA test? P(-|no cancer)=? (d) If a man gets an elevated PSA test (+), what is the probability that he...
According to a 2018 article in Esquire magazine, approximately 70% of males over age 70 will develop cancerous cells in their prostate, Prostate cancer is second only to skin cancer as the most common form of cancer for males in the United States. One of the most common tests for the detection of prostate cancer is the prostate-specific antigen (PSA) test. However, this test is known to have a high false positive rate (tests that come back positive...
A test for measurement of level of Prostate Specific Antigen (PSA) is a commonly used screening procedure for prostate cancer. Men with PSA levels greater than 10 nanograms per millilitre (ng/ml) (S) have 60% chance of prostate cancer (C), men whose PSA levels are between 4 ng/ml and 10 ng/ml (S) have 25% chance of having prostate cancer (C) and for men whose PSA levels are less than 4ng/ml (S), the risk of developing prostate cancer is 10% (C) Suppose...
Consider the following domain: . a % of men at age fifty who participate in the routine screen have prostate cancer. .b% of men with prostate cancer will get positive prostate-specific antigen test. • % of men without prostate cancer will also get positive prostate-specific antigen test. 1. Please describe the domain knowledge in terms of probabilities in which C is used to denote prostate cancer and P is used to denote positive prostate-specific antigen test. 2. Please follow Bayesian...
To prevent developing a certain type of cancer, Health Canada
organize a di- agnostic test. The false positive and negative rates
for this diagnostic test are five percent and four percent,
respectively. Assume that five percent of the population has this
type of cancer.
1. If a randomly selected person has a positive test result,
what is the prob- ability that the person has this type of
cancer?
2. The test is administrated twice on the same patient. Assume
that...

You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.17. You use a significance level of α=0.02. H0:p=0.17 H1:p≠0.17 You obtain a sample of size n=428 in which there are 56 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal...
