I believe question 3 is B and question 4 is B
Answer:
2v+2
Step-by-step explanation:
Answer:
X ~ N(27, 4) ;
xbar ~ N(27, 0.1026) ;
0.5 ;
0.5
Step-by-step explanation:
Probability distribution of X : N(μ, σ²)
μ = 27 ; σ = 2
X ~ N(μ, σ²) = X ~ N(27, 2²) ;X ~ N(27, 4)
Distribution is approximately normal ; μ = xbar ; xbar = 27
(Standard Error)² = (σ/√n)²= (2/√39)² = 0.1026
xbar ~ N(μ, σ²) = xbar ~ N(27, 2²) ; xbar ~ N(27, 0.1026)
Probability that a randomly selected individual found a job in less than 27 weeks :
P(X < 27) :
Obtain the Zscore :
Z = (x - μ) / σ
Z = (27 - 27) / 2 = 0/2
Z = 0
P(Z < 0) = 0.5
D.) n = 36
P(X < 27) :
Obtain the Zscore :
Z = (x - μ) / σ/√n
Z = (27 - 27) / (2/√36) = 0/0.33333
Z = 0
P(Z < 0) = 0.5
Answer:48/12 is how you solve this so your answer is 4 BRAINLY PLZZZZZZZZZZ
Step-by-step explanation:
The variable which is a categorical variable among the answer choices as in the task content is; Population of the state.
<h3>What is the categorical variable among the answer choices?</h3>
Categorical variables represent types of data which may be divided into groups. Instances of categorical variables include but are not limited to race, sex, age group, and gender.
It therefore follows from the traditional definition of categorical variables that the answer choice which represents a categorical variable is; Population of the state.
