Answer:
b) B and D and c) A and C
Step-by-step explanation:
The hypotheses would be:
(Right tailed test at 5% level)
Sample proportions are
Sample A B C D
Success 31 34 27 38
Proportion p 0.775 0.85 0.675 0.95
Std error
(sqrtpq/n) 0.066 0.056 0.074 0.034
p diff
p-0.75 0.025 0.10 - 0.075 0.20
Z stat
p diff/SE 0.0757 1.77 1.01 5.80
p value 0.469 0.038 0.156 0.000001
we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.
b) Only B and D provide against the null. Because p <0.05
c) A and C provide no evidence for the alternative because p >0.05

Answer: The equation has one solution
Step-by-step explanation: First , open the brackets
7( 12 - 2x ) = 4 (3 - 3x )
84 - 14x = 12 - 12x
collect the like terms
84 - 12 = - 12x + 14x
72 = 2x
Therefore divide through by 2
x = 72/2
x = 36
Therefore, the equation has only one solution
