was a railroad worker in Communist Poland who went into a coma in 1988 after getting hit by a train. When he woke up in 2007, after 19 years in a coma, the Soviet Union and the Warsaw Pact had been overthrown, food rationing had ended, and Poles everywhere were walking around with mobile phones. Since a coma is a state of unconsciousness without wakefulness, Grzebski's 19 years in a coma certainly counts as sleep.

A pharmacist receives a shipment of 22 bottles of a drug and has 4 of the bottles tested. If 6 of the 22 bottles are contaminate

romanna [79]

Explanation:

A hypergeometric distribution as a function of statistical distribution where members from two groups are analysed, without replacing those members. Unlike binomial distributions, in which the probability remains the same for each trial, in hypergeometric distributions, these members are not replaced- each trial's probability affects the probability within next trial.

This is used in the process of random sampling and as a means of quality control in statistics; for example selecting members of a sports team from a mixed population of boys and girls.

Hypergeometric Formula..,

For a population consisting of N items, k are successes. And a random sample from that population consisting of n items, x of which are successes.

∴ hypergeometric probability is:

h(x; N, n, k) = [ kCx ] [ N-kCn-x ] / [ NCn ]

this distribution always has...

its mean= n * k / N .
its variance is n * k * ( N - k ) * ( N - n ) / [ N2 * ( N - 1 ) ] .

Thus….

Total number of bottles = 22

Number of contaminated bottles = 6

Number of tested bottles = 4

X= a random variable representing the number of contaminated bottles selected for the test.

N = 22

K = 6

n = 4

The probability mass function, f(x), is given by...

P(X=x)) = [ kCx] [ N-kCn-x ] / [ NCn ] x= 0,1,2,3,...,n

= $\frac{[6 C 1] [22-6 C 4-1]}{[22 C 4]}$

$\frac{C\left \ {{k=6} \atop {x=1}} \right. C\left \ {{22-6} \atop {4-1}} \right. }{C \left \ {22} \atop {4}} \right. }$

$Cxk= C14= 4!(1!(4 - 1)!)^{-1}= 24(6)^{-1}= 4\\Cn-xN-k=C\left \ {{22-6} \atop {4-1}} \right. } =16!(4!(16-4)!)^{-1}\\(CnN)^{-1}=(C \left \ {{y=22} \atop {x=6}} \right. ) ^{-1}=[22!(6!(22-6)!)^{-1}]^{-1}$

f(x)= p= P(X=1)=0.45933014354067

P(that more than 1 of the tested bottles is contaminated);

P(X>1)=1−P(X≤1)=1−(P(X=0)+P(X=2))

P(X>1)=0.291866028708134

Probability that one is contaminated: 0.4593(4 dec places)

Probability that more than one is contaminated: 0.2919 (4 dec places)

Which factor influences the early detection of a childhood disease by a physician?

frez [133]

A. "The child's diet" is a factor that influences the early detection of a childhood disease by a physician. An unhealthy diet will probably cause problems in health, which for a child who does have a healthy diet will not need to suffer. B. can affect a child mentally, but it won't cause a childhood disease. And C. and D. are just silly. A child will not get a disease based on how close the doctor's office is or if the kid is in school or not. Hope this helped!
