In designing an experiment involving a treatment applied to 4 test​ subjects, researchers plan to use a simple random sample of
erik [133]

Answer:

The probability is  p(n ) = 3.18*10^{-5}

Step-by-step explanation:

From the question we are told that

     The population size is  N =  31

      The sample size  n =  4  

 

Generally the number of way by which the n  can be selected from N is mathematically represented as

          \left  N} \atop {}} \right. C_n =  \frac{N! }{(N-n)!n!}

=>       \left  31} \atop {}} \right. C_4 =  \frac{31! }{(31-4)!4!}

=>       \left  31} \atop {}} \right. C_4 =  \frac{31 * 30 * 29 * 28* 27! }{27! *  4*3 * 2 * 1 }

=>        \left  31} \atop {}} \right. C_4 =  \frac{ 755160 }{ 24}

=>        \left  31} \atop {}} \right. C_4 = 31465

The number of ways of selecting a particular sample size is  is   k =  1

Therefore the probability of each simple random sample in this​ case is mathematically evaluated as  

           p(n ) =  \frac{1}{31465}  

           p(n ) = 3.18*10^{-5}

Write a linear function f with f(0) =7 and f(3)=1
swat32

Answer:

  f(x) = -2x +7

Step-by-step explanation:

The 2-point form of the equation for a line is suitable for this. For points (x1, y1) and (x2, y2), the equation is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

For the given points (0, 7) and (3, 1), the equation is ...

  y = (1 -7)/(3 -0)(x -0) +7

  y = -6/3x +7 . . . . . . . . simplify.

We can use f(x) for y to get ...

  f(x) = -2x +7
