Answer:
0.71875
Step-by-step explanation:
Probability that a person thinks of himself as Democrat = P(A)= 0.32
Probability that a person agress that the govt. in Washington should do everything possible to improve the standard of living of poor= P(B)
Probability that a Democrat agress that the govt. in Washington should do everything possible to improve the standard of living of poor P(A ∩ B) = 0.23
P(B/A) = P(B∩A)/ P(A)
P(B/A)= 0.23/0.32
P(B/A) = 0.71875
Answer:
No ;
Step-by-step explanation:
Given ;
s2 = 10 ; n2 = 10 ; s1 = 12 ; n1 = 12
Hypothesis :
H0 : σ1² = σ2²
H1 : σ1² ≠ σ2²
The test statistic :
Ftest = s1² / s2² = 12² / 10² = 144 / 100 = 1.44
The Pvalue using the Pvalue from Ftest calculator :
Numerator df = 12 - 1 = 11
Denominator df = 10 - 1 = 9
Pvalue = 0.2969
At α = 0.1
If Pvalue > α ; Fail to reject H0
0.2969 > 0.1 ; Hence, we fail to reject the Null
Hence, we cannot conclude that variation exists
