Answer:
p ( x > 2746 ) = p ( z > - 1.4552 )
= 1 - 0.072806
= 0.9272
This shows that there is > 92% of a republican candidate winning the election hence I will advice Gallup to declare the Republican candidate winner
Step-by-step explanation:
Given data:
51% of male voters preferred a Republican candidate
sample size = 5490
To win the vote one needs ≈ 2746 votes
In order to advice Gallup appropriately lets consider this as a binomial distribution
n = 5490
p = 0.51
q = 1 - 0.51 = 0.49
Hence
> 5 while
< 5
we will consider it as a normal distribution
From the question :
number of male voters who prefer republican candidate ( mean ) ( u )
= 0.51 * 5490 = 2799.9
std =
=
= 37.0399 ---- ( 1 )
determine the Z-score = (x - u ) / std ---- ( 2 )
x = 2746 , u = 2799.9 , std = 37.0399
hence Z - score = - 1.4552
hence
p ( x > 2746 ) = p ( z > - 1.4552 )
= 1 - 0.072806
= 0.9272
This shows that there is > 92% of a republican candidate winning the election hence I will advice Gallup to declare the Republican candidate winner
Its letter D
7(19)-21 (x=19)
133-21=112 (RZ)
112+112=224 (RT)
There are 2 ways to do this...
19,500(1.06) = 20,670
or
19,500 + 0.06(19,500) = 19,500 + 1170 = 20670
a) Aiden's taxable income is $50,450.
The taxable income is equal to the gross income minus the standard deduction.
= $50,450 ($63,000 - $12,550).
b) Aiden's marginal tax rate = 22% (for taxable income falling under the income bracket of $40,526 to $86,375 for the tax 2021 year. It is assumed that Aiden is single.
c) Aiden's effective tax rate = 13.72%. The effective tax rate = total taxes due divided by Aiden's taxable income.
= 13.72% ($6,922/$50,450 x 100)
