Problem 6 A website for home pregnancy test cites the following: "When the subjects using the test were women who collected and tested their own samples, the overall sensitivityl was 75%. The specificity2 was 52%. Suppose a subject has a positive test and that 30% of women taking pregnancy tests are actually pregnant. [1] Sensitivity: probability that the test is positive given that the subject is pregnant. [2] Specificity: probability that...

Suppose that 60 percent of women who purchase over the counter pregnancy tests are actually pregnant. Call this event B. 1. what is Bc? 2. the probability that the pregnancy test id positive given that the person is pregnant is 0.96 (true positive). what is the probability that the pregnancy test is negative given that the person is pregnant? (False negative). 3. the probability that the pregnancy test is positive given that the person is not pregnant is 0.01 (false...

Janelle is taking a pregnancy test. She estimates that 0.5% of women at any given time are pregnant. Janelle takes an over-the-counter pregnancy test. The test tests positive (says your pregnant) for pregnant women 90% of the time. It gives a false positive 10% of the time. Janelle tests positive (the test says she is pregnant). What is the probability that Janelle is actually pregnant? Use a tree diagram and Bayes theorem to show if Janelle is actually pregnant.

1-3. In 2010, in the U.S., the pregnancy rate among women 15-44 was 9.8%. There are many pregnancy tests out there. Nancy decided to use AccuBaby, because she saw the relatively high "accuracy" number (97% accurate). Accuracy is often misunderstood and confused with other measures like sensitivity and precision. We will interpret accuracy as the probability that a woman who is pregnant tests positive, and the probability of receiving a negative result if she is not pregnant. That...

A test to determine whether a certain antibody is present is 99.299.2% effective. This means that the test will accurately come back negative if the antibody is not present (in the test subject) 99.299.2% of the time. The probability of a test coming back positive when the antibody is not present (a false positive) is 0.0080.008. Suppose the test is given to fourfour randomly selected people who do not have the antibody.(a) What is the probability that the test comes...

According to Health magazine (July/August 1992), the probability of pregnancy in the first year is 0.12 for typical users of condoms (which include couples who occasionally forget to use the method or dont use it correctly). However, the probability of pregnancy is only 0.02 for perfect il ers those who use the condom correctly each time) (a) List all the prod 1 litirs given in this prol İnti, e prewed in terms of events that you d fine.

4.4 Gestational diabetes mellitus (GDM) is a condition that causes serious adverse perinatal outcomes in pregnancy. It is estimated that approximately 11.7% of women have GDM during pregnancy. A clinic trial was initiated to test a screening method for GDM among 37 pregnant women who had GDM and 33 pregnant women without GDM. The results are listed below Test (+) 36 Test (-) Total 37 Women with GDM Women without GDM 31 a) What is the sensitivity? b) What is...

Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean μ=283 days and σ=17 days. (a) What is the probability that a randomly selected pregnancy lasts less than 277 days? The probability that a randomly selected pregnancy lasts less than 277 days is approximately 0.3632 (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. (Round to the...

The probability that a randomly selected pregnancy lasts less than 268 days is approximately select: 0.3773 0.3773. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. (Round to the nearest integer as needed.) A. If 100 pregnant individuals were selected independently from this population, we would expect 1 1 pregnancies to last exactly 268 days. B. If 100 pregnant individuals were selected independently from this...
