Identify the variable in the information below. ​ Consider a wildlife reserve known for its diverse ecosystem. Researchers are interested in understanding the distribution of a specific species of birds within the reserve. To estimate the population density of these birds, a random sample of 60 observation points, each covering an area of 200 square meters, is selected. The researchers record the number of bird nests in each observation point as an indicator of the bird population density in the region.  

Diagnostic tests of medical conditions have several results. The rest result can be positive or negative. A positive test (+) indicates the patient has the condition. A negative test (–) indicates the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 201 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown.     Condition Present Condition Absent Row Total Test Result + 119 18 137 Test Result – 18 46 64 Column Total 137 64 201 ​ Assume that the sample is representative of the entire population. For a person selected at random, find P(getting test result – or condition present). Round your answer to the nearest hundredth.

You draw two cards from a standard deck of 52 cards, but before you draw the second card, you put the first one back and reshuffle the deck. If you get a 3 on the first card, find the probability of drawing a 3 for the second card. ​

A probability and statistics Professor is writing an exam that consists of nine problems. In how many ways can these nine problems be re-ordered?

A shipment of 100 parts has arrived, and a quality control engineer must inspect a random sample of 10 parts. The probability of a defective part is 15%. The engineer will reject the shipment if more than 2 out of the 10 parts are defective. What is the probability the shipment will be rejected?

In a certain population 95% of the population does not have a certain STD. A medical test has been devised that detects the STD 90% of the time in individuals who have the STD. The test also confirms that individuals who do not have the STD correctly 85% of the time. What is the probability an individual has an STD and tests positive?
