3, A hospital is treating patients who have Lhassa Fever, 70% of patients with this disease die, and each patient lives or dies independently of other patients. a. If there are currently 12 Lhassa Fever patients in the hospital, find the probability that6 or fewer die. b. If there are currently 12 Lhassa Fever patients in the hospital, find the probability that 6 or more die. If the hospital has 8 Lhassa Fever patients, find the probability that all die....

29. Suppose it is believed that the probability a patient will die from a certain disease following treatment is 0.1. In a group of 150 such patients, the number who do not die would have mean and standard deviation_ (given to two decimal places).

Leave blank 7. A drugs company claims that 75% of patients suffering from depression recover when treated with a new drug. A random sample of 10 patients with depression is taken from a doctor's records (a) Write down a suitable distribution to model the number ofpatients in this sample who recover when treated with the new drug. Given that the claim is correct, (b) find the probability that the treatment will be successful for exactly 6 patients. The doctor believes...

(3) Suppose the length of stay in a chronic disease hospital of a certain type of patient has the mean of 60 days with a standard deviation of 15 days. It is reasonably to assume an approximately normal distribution of the lengths of stay (a) If one patient is selected from this group at random, what the probability that this patient will have a length of stay between 50 and 90 days? at is selected from this group at random,...

A scientist designed a medical test for a certain disease. Among 100 patients who have the disease, the test will show the presence of the disease in 96 cases out of 100, and will fail to show the presence of the disease in the remaining 4 cases out of 100. Among those who do not have the disease, the test will erroneously show the presence of the disease in 3 cases out of 100, and will show there is no...

7. Records show that a treatment for a rare disease is effective 70% of the time. Suppose that a random sample of 18 patients undergoes this treatment. (a) Find the probability that the treatment will be successful for (i) exactly 13 patients iii) under 10 patients(ii) at least 13 patients (iv) 10 to 15 patients inclusive (b) Find: () the mean (expected) number patients for which the treatment will be successful (ii) the variance and standard deviation

The probability that an individual randomly selected from a particular population has a certain disease is 0.04. A diagnostic test correctly detects the presence of the disease 94% of the time and correctly detects the absence of the disease 96% of the time. If the test is applied twice, the two test results are independent, and both are positive, what is the (posterior) probability that the selected individual has the disease? [Hint: Tree diagram with first-generation branches corresponding to Disease...
