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
From previous experience, the owner of an apple orchard knows that the mean weight of Gala apples is 140 grams. There has been more precipitation than usual this year. The owner believes the weights of the apples will be heavier than usual and therefore the crop will be more profitable. This will allow the owner to expand the orchard. The owner takes a random sample of 30 apples and records their mean weight. What is the consequence of a Type I error in this situation?
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually greater than 140 grams.
The owner believes the crop will not be more profitable and does not expand the orchard when the true mean weight of the apples is actually greater than 140 grams.
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
The owner believes the crop will not be more profitable and does not expand the orchard when the true mean weight of the apples is actually not greater than 140 grams.
Answer:
C, The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
Step-by-step explanation:
Using error concepts, it is found that the consequence of a Type I error in this situation in this situation is given by:
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
What are the hypotheses test?At the null hypotheses, it is tested if the weights are not heavier, that is:
[tex]H_0: \mu = 140[/tex]
At the alternative hypotheses, it is tested if they are heavier, that is:
[tex]H_1: \mu > 140[/tex]
A Type I error is the rejection of a true null hypothesis, that is, concluding that the weights are heavier and more profitable when they are not. Hence the correct option is:
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.

11. What is the center of the circle (x - 2)2 + (y + 6)2 = 25?
Please help and add explanation
Answer:
y=-3x+10
Step-by-step explanation:
Since you know that the equation of the line is perpendicular to 1/3, you have to find the inverse of 1/3. You swap the denominator and numerator and make the number negative. In this case, it will be -3. Now that you know the slope is -3, you can use the equation y-y1=m(x-x1) where m is the slope. We know that the point (2,4) is in the graph so we can plug it into the equation. y-4=m(x-2). We know that the slope is -3 so we can plug it into the equation. y-4=-3(x-2). Simplify this to get y-4=-3x+6. Simplify this to get y=-3x+10. This means that the answer is y=-3x+10.

An NBA fan named Mark claims that there are more fouls called on his team any other team, but the commissioner says that the number of fouls called against his team are no different than any other team. Mark finds that the average number of fouls in any game in the NBA is 11.5. He takes a random sample of 34 of games involving his team and finds that there are an average of 12.2 fouls against his team, with a standard deviation of 1.6 fouls. What is the correct conclusion
Answer:
Fouls > Average Fouls
Step-by-step explanation:
Null Hypothesis [ H0 ] : Fouls = Average Fouls ie 11.5
Alternate Hypothesis [ H1 ] : Fouls > Average Fouls
t = ( x - u ) / ( s / √n )
where x = actual observed mean = 12.2 here , u = assumed population mean = 11.5 , s = sample standard deviation = 1.6 , n = sample size = 34
So, t = (12.2 - 11.5 ) / ( 1.6 / √34 ) = 0.7 / ( 1.6 / 5.83 ) = 0.7 / 0.275 = 2.55
t tabulated value for α = 5% right tailed = 1.645 , ie < calculated value 2.55 So , we reject the null hypothesis, & conclude that 'Fouls > Average Fouls'

Answer:
El comerciante NO PUEDE guardar todas las cajas de zapatos en el cajón
Step-by-step explanation:
Tenemos que encontrar el volumen de la caja.
Se nos dice en la pregunta que:
Coloca 20 a lo largo, 7 a lo ancho y 8 a la altura.
Volumen = Largo × Ancho × Alto
Largo = 20, Ancho = 7, Alto = 8
Volumen = 20 × 7 × 8
= 1120
También se nos dice que: el comerciante tiene 1108 cajas de zapatos y quiere guardarlas en el cajón de su camión.
Comparando esto con nuestro cálculo anterior, el comerciante NO PUEDE guardar todas las cajas de zapatos en el cajón

Miguel weighs himself and discovers he weighs 83,600 grams. How many kilograms does Miguel weigh?
The solution is, 83.6 kilograms does Miguel weigh.
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
here, we have,
given that,
Miguel weighs himself and discovers he weighs 83,600 grams.
now.,, we have to find that how many kilograms does Miguel weigh.
we know that,
1000 grams = 1 kg
so, we have,
he weighs 83,600 grams
so,
as, 1000 grams = 1 kg
so, 1 gram = 1/1000 kg
we get,
83,600 grams = 1/1000 * 83,600 kg
i.e. 83,600 grams = 83.6 kg
Hence, 83.6 kilograms does Miguel weigh.
