An analysis of personal loans at a local bank revealed the following facts: 10% of all personal loans are in default (D), 90% of allpersonal loans are not in default (D'), 20% of those in default are homeowners (HID), and 70% of those not in default are homeowners(H | D'). If a personal loan is selected at random P (H _n D') = _____.0.630.78O 0.200.180.90

P(D)=10% , P(D')=90%, P(H|D)=20%, P(H|D')=70% P(H∩D′)=?

The population of children under 5 years in Whitefish, Montana on July 1 2015 was 2,350 with no population change reported for the next year. In that year, in a daycare of 150 children under 5 years in Whitefish, Montana, 50 of them develop Respiratory Syncytial Virus (RSV). During the next 3 months, 8 of the children with RSV died with 5 of them being reported to be associated with RSV infection. No other deaths were reported among children under 5 years in this town. The incidence of RSV would be [Select the option closest to your answer] A. 0.02% B. 2.2% C. 33.3% D. 3.3%

A postmix beverage machine is adjusted to release a certain amount of syrup into a chamber where it is mixed with carbonated water. A random sample of 25 beverages was found to have a mean syrup content of x = 1.10 fluid ounces and a standard deviation of s = 0.015 fluid ounces. a. Compute a 95% prediction interval on the syrup volume in the next beverage dispensed. Compare the length of the prediction interval with the length of the 95% CI on the population mean. b. Compute a 95% tolerance interval on the syrup volume that has a confidence level of 90%. Compare the length of the tolerance interval with the length of the 95% CI on the population mean.
Incidence rate refers to new cases for 'collective time at-risk' that can be measured as person-years, person-months or even person-days etc. A three-year study reported a total of 3538 cases at the end and this total included old or pre-existing 605 cases identified at baseline. Please calculate incidence rate if total time at risk is 14155 person-years. NOTE: Calculate Incidence rate as per 1000 person-years & type in only your final answer with two decimals. Correct rounding and use of brackets on your calculator are essential.
Based on Information from a previous study, r, = 39 people out of a random sample of n, 98 adult Americans who did not attend college belleve in extraterrestrials. However, out of a random sample of n, = 98 adult Americans who did attend college, r, = 46 clatm that they believe in extraterrestrials. Does this Indicate that the proportion of people who attended college and who beleve in extraterrestrials is higher than the proportion who did not attend college? Use a = 0.01.

A common characterization of obese individuals is that their body mass index is at least 30 [BMI = weight/(height)2, where height is in meters and weight is in kilograms]. An article reported that in a sample of female workers, 264 had BMIS of less than 25, 158 had BMIS that were at least 25 but less than 30, and 122 had BMIS exceeding 30. Is there compelling evidence for concluding that more than 20% of the individuals in the sampled population are obese?

25. An experimenter has prepared a drug that he claims has side effects in 25% or less of those people taking it (considerably less than the current medication). In an attempt to verify the claim, his prescribed drug was administered to 24 patients & Y, the # of patients having side effects by the drug, was observed. If at most 9 patients have side effects with this drug the claim is accepted (as valid). Find P (Type II Error) when p = 0.75 0.000112 0.000523 O 0.595599 None of the other answers are correct.
