Now, suppose assuming the true fraction of voters is .65, the estimated standard deviation of X is given as 6.65. Suppose you find that 115 people actually voted yes in the random sample of 200. Conduct hypothesis testing using p value approach at 5% significance level to determine the validity of Candidate A’s claim that he was at least supported by 65% of the voters. (Make sure you show the steps of hypothesis testing)
Answer:
reject H0 ; conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters
Step-by-step explanation:
x = 115
n = 200
Phat = x / n = 115 / 200 = 0.575
H0 : P0 ≥ 0.65
H1 : P0 < 0.65
TEST STATISTIC :
Phat - P0 ÷ sqrt[(P0(1-P0))/n]
0.575 - 0.65 ÷ sqrt[(0.65(0.35))/200]
-0.075 ÷ 0.0337268
Test statistic -2.237
Pvalue :
P(Z < - 2.237) = 0.012643
α = 0.05
Pvalue < α
0.012643 < 0.05 ; We reject H0
We can conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters

Rewrite the function in standard form.
f(x) = 4(x - 2)^2+ 3
Answer:
f(x) = 4x^2 - 13
Step-by-step explanation:
f(x)=4(x-2)^2 + 3 parentaties first
f(x) = 4 (x^2 - 4)+ 3 multiply by what's infront parentaties
f(x) = 4x^2 - 16 + 3 combine light terms
f(x) = 4x^2 - 13 Answer

Sketch the graph of the following equations: y=x+5, y=-(x+5), and y = |x+5|
The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Equations are,
y = x + 5
y = - (x + 5)
y = |x + 5|
Since, All equations shows equation of line.
Hence, We can draw all the equations as shown in figure.
y = x + 5
Slope = 1
y - intercept = 5
y = - x - 5
Slope = - 1
y - intercept = - 5
Thus, The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.

Answer:
44 minutes
Step-by-step explanation:
Given that :
Start time = 1:37 pm
End time = 2:21 pm
The time difference is obtained by subtracting the start time from the end time :
. End time - start time
2:21 pm - 1:37 pm
From 1:37 pm to 2 pm = 23 minutes
From 2 pm to 2:21 pm = 21 minutes
Total minutes = (23 + 21) minutes = 44 minutes

Hollis put a layer of boxes in the bottom of a container. Each box has a volume of 1 cubic foot. The base layer of boxes in the container in shown. Hollis will need 8 of these layers to completely fill the container. What is the volume of the container in cubic feet?
Answer:
288 ft³
Step-by-step explanation:
Given that
The volume of each box is 1 cubic foot
And, Hollies required 8 of these layers
Now based on the above information
We assume that the dimension of the base layer is 6 by 6
So, the volume of the container is
= Length × Width × Height
where,
Length = 6 ft
Width = 6 ft
And, Height = 8 ft
So,
= 6 ft × 6 ft × 8 ft
= 288 ft³

ABC is a straight line. Work out the size of the angle marked x
Answer:
x = 57°
Step-by-step explanation:
angles on a straight line add up to 180°. to work out x, we need to subtract 70 and 53 from 180, to get the remaining angle, aka angle x. 180-70=110.
110-53= 57. therefore, x = 57°.
The measure of angle x in the straight line ABC is 57 degrees
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the diagram:
x + 53 + 70 = 180° (sum of angles in a straight line).
Hence:
x = 57°
The measure of angle x in the straight line ABC is 57 degrees
