Take any two points from the table and find the slope.

Points:

(1,60) & (3,180)

\large \tt \: m =  \frac{ y_{2} -  y_{1}}{ x_{2}  -  x_{1}}

\sf \: m =  \frac{180 - 60}{3 - 1}

\sf \: m =  \frac{120}{2}

\sf \: m =  \cancel \frac{120}{2}  = 60

<em>Therefore, Slope is 60..</em>

What is the probability of selection for any man in a proportionate random sample, where a sample of 100 will be drawn from a po
kolbaska11 [484]
Working Principle: Stratified Random Sampling

nx = (Nx/N)*n

where:
    nx = sample size for stratum x
    Nx = population size for stratum x
    N = total population size 
    n = total sample size

Given:

  Nx = 100
  N = 1000
  n = 0.5*(1000) = 500

Required: Probability of Man to be selected

Solution:

nx = (Nx/N)*n
nx = (100/1000)*500 = 50 men

ny = (Nx/N)*n
ny = (100/1000)*500 = 50 women


Probability of Man to be selected = nx/(nx + ny)*100 = 50/(50+50)*100 = 50%

<em>ANSWER: 50%</em>
