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
Ok so for this problem you you divide 2/3 n by 2/3 and 7/8 by 2/3
you get
to divide fraction you flip the divider over to find the reciprocal
2/3 > 3/2 also you change the division symbol to the multiplication symbol
the equation now is
now you multiply to get 21/16
the answer is 1 5/16 after you simplify it
