What is the probability that a randomly-selected patient is obese or is diagnosed withhypertension?P (Obese or Hypertension):Round to 3 significant digitsb. What is the probability that a randomly-selected patient is not at an increased risk(i.e. not have both effects simultaneously)?P(Not at an increased risk):Round to 3 significant digitsLSUBMIT QUESTIONSAVE PROGRESSSUBN

A country has a population of 21M people. Some people received a certain treatment and some didn’t. Table 1 shows the disease rates based on age and treatment status. The treatment has no side effects, and only changes the probability that someone contracts this (undesirable) disease. Age Untreated Treated People Disease Disease per 100K People Disease Disease per 100K young 5,000,000 40 0.8 5,000,000 20 0.4 old 1,000,000 60 6.0 10,000,000 300 3.0 Table 1: Disease rates based on age and treatment status. (a) Define the following events and compute four conditional probabilities of contract- ing the disease based on a person’s age and based on their treatment status. The events are D:= contracting the disease, Y := young, O:= old, T:= treated, and U:=untreated. Note that O = Y c, and similarly for T and U. Now, calculate 4 probabilities like P(D|T, Y ) for each possibility. (b) What is the probability of contracting the disease if you are treated? Untreated? (c) Based on…
A Food Marketing Institute found that 26% of households spend more than $125 a week on groceries. Assume the population proportion is 0.26 and a simple random sample of 291 households is selected from the population. What is the probability that the sample proportion of households spending more than $125 a week is less than 0.23?

Bananas have an average rotting rate of 0.1%. A banana shipping company boxes bananas 48 to a box. Quality control randomly chooses a box and then chooses 4 bananas.

Flying over the western states with mountainous terrain in a small aircraft is 40% riskier than flying over similar distances in flatter portions of the nation, according to a General Accounting Office study completed in response to a congressional request. The accident rate for small aircraft in the 11 mountainous western states is 3.5 accidents per 100,000 flight operations. (c) Find the probability of at least 2 accidents in 180,000 flight operations. (Use 4 decimal places.)

Consider the following passage: I ran a regression, with many variables to predict the result of another variable which was the murder rate. One can see that lots of things, can cause the murder rate to increase or decrease. I tried to account for all the important factors, and those factors are the SAT scores, unemployment rate, and international migration per 1,000. The SAT score is, average combined total score participants did on the SAT exam. The unemployment rate is, "a measure of the prevalence of unemployment and it is calculated as a percentage by dividing the number of unemployed individuals by all individuals currently in the labor force." (Wikipedia) International migration per 1,000 is, the number of people who come into a state from other countries per 1,000 people who live in the state. After I run the regression I will look at the t scores and p values and I should hopefully conclude that international migration does not cause crime. Which writing mistakes, if any, did…
When a machine is improperly adjusted, it has probability 0.15 of producing a defective item. Each day, the machine is run until three defective items are produced. When this occurs, it is stopped and checked for adjustment. What is the probability that an improperly adjusted machine will produce five or more items before being stopped? What is the average number of items an improperly adjusted machine will produce before being stopped?
Bryan is performing data entry for an insurance company by taking handwritten records and entering them into the database. Thus far, 15.6% of the handwritten records have had missing data that prevented them from being entered into the database. If Bryan takes 10 handwritten records, what is the probability that at most three records will be incomplete?
