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>
Answer:
0.149
Step-by-step explanation:
Given that Jason wants to perform a two-tailed test for equality between two independent sample proportions
Each sample has at least 10 "successes" and 10 "failures."
Jason's test statistic is -1.44
Since here proportions are tested Z test might have been used.
Z statistic = -1.44
We can get p value for this Z statistic
p value=0.149
p value for two tailed is 0.149
Comparing this with t statistic we can decide whether to accept or reject null hypothesis.
