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 height is 8 yds
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) h where b1 and b2 are the lengths of the bases
108 = 1/2 ( 15+12) *h
108 = 1/2 ( 27)h
Multiply each side by 2
216 = 27h
Divide each side by 27
216/27 = 27h/27
8 =h
Answer:
3^10
Step-by-step explanation:
Because the rules of index
3^4 = 3*3*3*3
3^6 = 3*3*3*3*3*3
(3^4)(3^6)=
3*3*3*3*3*3*3*3*3*3 = 3^10
268.08
V=4/3(pi)r(cubed)
Plug and chug —> the volume of this sphere is about(squiggly equality sign) 268.08 feet
