A recent taste test showed that 85% of people liked a new chicken sandwich recently added to a restaurant’s menu. The restaurant manager claimed that only 68% liked the new sandwich. To determine whether this sample supports the population proportion of 0.85, a simulation of 100 trials is run, each with a sample size of 30 and a point estimate of 0.85. The minimum sample proportion from the simulation was 0.66 and the maximum sample proportion from the simulation was 0.88.
a) Estimate the margin of error using the half the range method.
b) Use your margin of error to find the interval estimate.
c) Based on the computed interval estimate, is the restaurant manager’s claim that 68% of people liked the new sandwich valid? Explain your answer.
Answer:
a) The margin of error = 0.11
b) The interval estimate = (0.74, 0.96)
c) Not valid because 68% = 0.68 is less than the values in the interval estimate
Step-by-step explanation:
The statistical data from the population and the simulation are;
The percentage of the people that liked the new chicken sandwich = 85% = The population proportion
The percentage the restaurant manager claims liked the new sandwich = 68%
The number of trials of the simulation = 100 trials
The sample size of each trial = 30
The point estimate of each trial = 0.85
The minimum sample proportion = 0.66
The maximum sample proportion = 0.88
a) The confidence interval = (0.66, 0.88)
By the half the range method, the margin of error is given by half the width of the confidence interval
∴ The margin of error, MOE = (0.88 - 0.66)/2 = 0.11
b) The interval estimate are the expected range of numbers for a parameters
The interval estimate = The point estimate ± MOE
∴ The interval estimate = 0.85 ± 0.11 = (0.74, 0.96)
Given that the manager's claim of 68% is not within the interval estimate, the manager's claim is not valid based on the expected values for the people that liked the new sandwich found with the point estimate and the margin of error

Answer:

Step-by-step explanation:
To breakeven means that you made exactly as much money as you spent, so if you spent $50 to make lemonade, you would need to make $50 in profits from selling to break even
first subtract the cost of making each horse from the price of selling each horse (you do this to find out how much profits he makes from one horse):
125 - 75 = 50
now divide 300 by 50 to find out how many horses need to be made to break even:
300 ÷ 50 = 6

Answer:
Log (1/x) = –0.9925
Step-by-step explanation:
From the question given above, the following data were obtained:
Log x = 0.9925
Log (1/x) =?
Recall,
Log (M/N) = log M – Log N
Thus,
Log (1/x) = Log 1 – Log x
Recall
Log 1 = 0
Log x = 0.9925
Thus,
Log (1/x) = Log 1 – Log x
Log (1/x) = 0 – 0.9925
Log (1/x) = –0.9925

The surface area of a figure is 736 in^2. If the dimensions are multiplied by 22, what will be the surface area of the new figure?
Answer:
356 224 in²Step-by-step explanation:
If the dimansions of a figure are multiplied by 22 then its surface is multiplied by 22²
736 in²·22² = 736 in²·484 = 356 224 in²

Point (4, –5) is mapped onto ________ when rotated 90° clockwise about the origin.
A)
(5, –4)
B)
(–5, 4)
C)
(5, 4)
D)
(–5, –4)
Answer:
D. (-5, -4)
Step-by-step explanation:
When making a rotation 90° clockwise, the coordinates will swap places. However, the x value will be the opposite and the y value will stay the same.
90° clockwise rule:
(x, y) ---> (y, -x)
(4, -5) ---> (-5, -4)

PLEASE HELP (15 POINTS!!) PLEASE
Answer:
(4,9)
Step-by-step explanation:
To solve this, you can use substitution or elimination. In this case I would use substitution. To do this, you have to isolate a variable. x is already isolated so we can skip this step. plug x into 5x-7y=-43. This will make the equation 5(2y-14)-7y=-43. Simplify this to get 10y-70-7y=-43. Simplify this to get 3y-70=-43. Add 70 in both sides to isolate y. This will make the equation 3y=27. Divide both sides by 3 to make y equal to 1. This will make the equation y=9. Now you know that y=9. Plug 9 into any equation. x=2(9)-14. Simplify this to get x=18-14. x=4. Now put the numbers as an ordered pair which is (x,y). We know that x=4 and y=9 so it is (4,9).

Phil melange 0.2L de jus de pomme teneur en fruit 25% et 0.1L de jus d'orange teneur de fruit 50% quel est la teneur en fruit de son cocktail
Answer:
10%
Step-by-step explanation:
La teneur en fruits de son cocktail est calculée comme suit:
25% de jus de pomme 0.2L + 50% de jus d'orange 0.1L
0.25 × 0.2 + 0.5 × 0.1
0.05 + 0.05
= 0.10
Conversion en pourcentage
= 0.10 × 100%
= 10%
Par conséquent, la teneur en fruits de son cocktail est de 10%

Tengo que leerme un libro de 1267 páginas en 3 semanas. La primera semana he leído 189 páginas y la segunda el triple que en la primera, ¿cuántas páginas me quedan por leer en la tercera semana?
Answer:
Quedan 511 páginas por leer en la tercera semana.
Step-by-step explanation:
Si el libro tiene 1267 y debe leerse en 3 semanas, se ha leído 189 páginas en la primera semana y 567 páginas en la segunda semana, es decir, el triple del número de páginas leídas en la semana anterior, la cantidad de páginas por leer para la tercera se determina mediante la siguiente sustracción:
[tex]x = 1267 - 189 - 567[/tex]
[tex]x = 511[/tex]
Quedan 511 páginas por leer en la tercera semana.
