Answer:
The answer is -1.2
Step-by-step explanation:
Recalling the standard deviation formula,
we have : σ = sqrt[ P * ( 1 - P ) / n ]
Where sqrt = square root
n = Number of derivative
Therefore,:
if, H0: p is not 48% vs H1: p1 = 48%
standard deviation is:
σ = sqrt[ P * ( 1 - P ) / n ] = sqrt[ .48*.49/900 ] = .01666333+
z -score is (p-P)/σ
= (.51-.53)/.01666333
The answer therefore = -1.2
ICONCLUSION:
It can therefore be concluded that there is statistical evidence that the proportions are different. H0 accepted in the hypothesis.
Answer:
x = 486956.5217
Step-by-step explanation:
5.75% of x = 28000
Of means multiply
Change the percent to a decimal
.0575 * x = 28000
Divide by .0575 on each side
.0575/.0575 * x = 28000/.0575
x = 486956.5217
There would be an open circle on positive 12 with the arrow moving to the right.

Step-by-step explanation:
<u>Calculate and compare:</u>
- A) $32000
- B) $18.5*35*52 = $33670
- C) $30000 + 5% = $30000 + $1500 = $31500
- D) $17.5*35*52 + $1500 = $33350
