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]}

OR          

\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)

<h3>B. In order for a fitness program to be fully effective, exercises that address all fitness components - cardio endurance, resistance training, and flexibility - must be incorporated on a regular basis. Focusing on just one of these components will hurt performance in other areas.</h3>

Explanation:

The Balance Principle in Sport refer to diversity. It dictates that all routines must be well proportion in order to achieve improvement.

Also, the balance principle dictates that the right mix of training activities are requires for optimal result. That is, have a good nutrition, workout each component to improve at almost every area like endurance, strength and flexibility.

It's important to say that the principle of balance also requires not going to extreme points, because can easily injure different parts of the body, due to its diversity.
