The report "The New Food Fights: U.S. Public Divides Over Food Science" states that younger adults are more likely to see foods with genetically modified ingredients as being bad for their health than older adults. This statement is based on a representative sample of 178 adult Americans aged 18 to 29 and a representative sample of 427 adult Americans aged 50 to 64. Of those in the 18 to 29 age group, 48% said they believed these foods were bad for their health, while only 3% of those in the 50 to 64 age group believed this.
(a) Are the sample sizes large enough to use the large-sample confidence interval to estimate the difference in the population proportions?
(b) Estimate the difference in the proportion of adult Americans aged 18 to 29 who believe the foods made with genetically modified ingredients are bad for their health and the corresponding proportion for adult Americans aged 50 to 64. Use a 90% confidence interval.
(c) Is zero in the confidence interval?
Answer:
a) yes
b) ( 0.0280 , 0.1720 )
c) No
Step-by-step explanation:
A) Determine if the sample sizes are large enough
where :
ages between ( 18 to 29 )
p1 = 0.48 ,
n1 = 178 , ∴ n1 P1 = 85.44 also n1 ( 1 - p1 ) = 92.56
ages between ( 50 to 64 )
P2 = 0.03 ,
n2 = 427 ∴ n2p2 = 12.81 also n2( 1 -p2 ) = 414.19
since all the values ae above 10 we can conclude that the sample sizes are large enough
answer = yes
B) Estimate the difference in the proportion of adult Americans aged 18 to 29
= ( 0.0280 , 0.1720 )
attached below is the detailed solution
C) zero is not included in the interval

A rectangular carport has area of one 50 ft.The width of the carport is 5 feet less than twice its length. Find the length and width of the carport
Width= ? feet,
Length= ? feet
Answer:
It is 10 because 5 times 10 is 50
Answer:
A) = 5
B) = 10
C) = (5 x 10)= 50
Step-by-step explanation:
Area of a rectangle a x b = c
Where a is the short side
Where b is the long side
And c is our area
Okay now we we have to think what numbers give us 50 so ( 1 x 50 , 5 x 10 , 2 x 25)
So since now we have the numbers we look for a number that is twice the other and is - 5 the other one and the only numbers are 10 and 5 so in conclusion
A= 5
B= 10
C= 50

Consider a taxi station at an airport where taxis and (groups of) customers arrive at times of Poisson processes with rates 2 and 3 per minute. Suppose that a taxi will wait no matter how many other taxis are present. However, if an arriving person does not find a taxi waiting he leaves to find alternative transportation. (a) Find the proportion of arriving customers that get taxis. (b) Find the average number of taxis waiting
Answer:
a) [tex]\pi(0)=\frac{1}{3}[/tex]
b) [tex]X=\frac{2}{3}[/tex]
Step-by-step explanation:
From the question we are told that:
Arrival time with Poisson's process =[tex]t_p=2-3minutes[/tex]
where
[tex]\lambda_1=2\\\lambda_2=3[/tex]
a)
Generally the equation Poisson's process is mathematically given by
[tex]\pi()n*\lambda_1=\pi(n+1*) \lambda_2[/tex]
[tex]\pi()n*2=\pi(n+1*)*3[/tex]
[tex]\pi(n+1)=\frac{2}{3} \pi+1*\pi(0)[/tex]
Therefore
[tex]\pi(0)(1+2/3+(2/3)^2+...)=1[/tex]
[tex]\pi(0)=\frac{1}{3}[/tex]
The proportion of arriving customers that get taxis.
[tex]\pi(0)=\frac{1}{3}[/tex]
b)
Generally the average number of taxis X waiting is mathematically given by
[tex]X=1-\pi(0)\\X=1-(1/3)[/tex]
[tex]X=\frac{2}{3}[/tex]

Find the measure of <2.
Answer:
78°
Step-by-step explanation:
In this problem, we need to find the value of angle 2.
Angle 2 is an Alternate exterior angle. Alternate exterior angles are formed by a transversal intersecting two parallel lines. They are located outside the two parallel lines.
To form an alternate exterior angle, angle 2 must be equal to 78°. Hence, we can say that the value of ∠2 is equal to 78°.

Use △GHJ, where A, B, and C are midpoints of the sides.
When GH = 7z−1 and CB = 4z−3, what is GA?
Answer:
GA=17
Step-by-step explanation:
As A, B, C are the midpoints of the sides of AGHJ,
so GH= 2(CB)
⇒7z-1= 2(4z-3)
⇒7z-1= 8z-6
⇒7z-8z= -6+1
⇒-7= -5
z=5
so GA=CB
⇒GA= 4(5)-3= 17
hope it helps...

The value of the variable 'z' is 5. Then the length of GA will be 17 units.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Use △GHJ, where A, B, and C are midpoints of the sides. When GH = 7z − 1 and CB = 4z − 3.
From the graph, then the condition is given as,
GH = 2 × BC
7z - 1 = 2 × (4z - 3)
Simplify the equation, then we have
7z - 1 = 2 × (4z - 3)
7z - 1 = 8z - 6
6 - 1 = 8z - 7z
z = 5
Then the length of the GA is given as,
GA = BC
GA = 4z - 3
GA = 4 (5) - 3
GA = 20 - 3
GA = 17 units
The value of the variable 'z' is 5. Then the length of GA will be 17 units.

A study finds that the number of gallons of water used each month per household in a
residential neighborhood are normally distributed with a mean of 470 gallons and a
standard deviation of 50 gallons. A household is randomly selected. What is the
probability that the household uses 480 gallons of water or less per month?
Answer:
0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 470 gallons and standard deviation of 50 gallons.
This means that [tex]\mu = 470, \sigma = 50[/tex]
What is the probability that the household uses 480 gallons of water or less per month?
This is the pvalue of Z when X = 480. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{480 - 470}{50}[/tex]
[tex]Z = 0.2[/tex]
[tex]Z = 0.2[/tex] has a pvalue of 0.5793
0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month
What is the range of the function graphed below?
Answer:
-3<y<=3 or B
Step-by-step explanation:
first we find the smallest y value which is -3
then we find the largest y vlaue which is three
so since there is an open circle at negative three we do not include it while at three we do.
so the answer would be -3<x<=3

Answer:
A: 8x +24
B: not equivalent for any value of x
Step-by-step explanation:
Part A:
The factor of 4 on the outside of parentheses multiplies each term inside:
M = 4(2x) +4(6)
M = 8x +24 . . . . . expression equivalent to M
__
Part B:
Expressions M and N are not equivalent for any value of x. They are equivalent if their difference is zero or can be made to be zero. Subtracting N from M, we find the difference to be ...
M -N = (8x +24) -(8x +10) = 14
There is no value of x that will make the difference of 14 become zero.
