It is estimated that 5.9% of Americans have diabetes. Suppose a medical lab uses a test for diabetes that is 98% accurate for pe

ople who have the disease and 95% accurate for people who do not have it. Find the conditional probability that a randomly selected person actually has diabetes given that the lab test says they have it.

Answer:

P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725

Explanation:

A probability is a number, between 0 and 1, expressing the precise likelihood of an event happening.

Probability (person actually has diabetes) = 5.9%

P(lab test says that they have diabetes) = 0.0764

P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725

Does the size of a bouncy ball affect the bounce hight
Inessa [10]
I'm pretty sure it does. Because if the ball was small, it bounces more higher than a ball that is big. It has much more mass and density.

Blue jays and crows eat caterpillars and mice. if the number of blue jays increases, what are the two likely effects on other po
suter [353]

If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.

<h3>What are two likely effects on other populations due to the increment in Blue jays population?</h3>
  • An organism that preys on other species in order to consume them as food is referred to as a predator.
  • Prey is a term used to describe an organism that a predator kills.
  • An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
  • Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
  • Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.

Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.
