The mean operating cost per hour for the current production method at S-E Electronics equals $220. A new production method will be implemented if ahypothesis test based on sample data suggests the new method reduces (v. the current method) the mean operating cost per hour.
Required:
a. State the null and alternative hypotheses associated with the test.
b. What is the Type I Error for the test and what are the business consequences of a Type I Error?
Answers
Answer:
H0 : μ = 220
H0 : μ < 220
Rejecting the null when it is actually true
We incorrectly drop a better method.
Step-by-step explanation:
The null hypothesis, H0
H0 : μ = 220
H0 : μ < 220
A type 1 error is committed when a true null hypothesis is incorrectly rejected. This means that we conclude that new method reduces the mean operating cost per hour when in fact it hasn't.
The impact of this on business is that the new method is adopted in place of the old method thinking it works better Than the old method.

What are the coordinates of the turning point of the parabola whose equation is y=-x^2+4x+1
PLEASEEE ANSWERRRRRR
Answers
Answer:
The maximum of the parabola lands at (2,5).
The coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)
What is Coordinate system?
A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points.
The equation of Parabola is y=-x²+4x+1
The turning point (vertex) is the point where the derivative is equal to zero.
y=-x²+4x+1
Differentiate the equation
dy/dx=-2x+4
Now equate dy/dx with zero
dy/dx=0
-2x+4=0
-2x=-4
x=2
Now put x value in the equation
y=-(2)²+4(2)+1
y=-4+8+1
y=5
Hence the coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)

Log (14\3) + log(11/5) - log(22/5) = log(?)
Answers
Answer:
The answer would be 7
Step-by-step explanation:
The equivalent value of the logarithmic equation is x = 7/3
What is Logarithm?
The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log AB
log A − log B = log A/B
log Aⁿ = n log A
Given data ,
Let the logarithmic equation be represented as A
Now , the value of A is
A = log ( 14/3 ) + log ( 11/5 ) - log ( 22/5 )
On simplifying , we get
From the properties of logarithm , we get
log A + log B = log AB
log A − log B = log A/B
So , A = log (14/3) + log (11/5) - log (22/5) = log [(14/3) × (11/5) / (22/5)]
A = log [(14/3) × (11/5) × (5/22)]
A = log ( 14/3 /2 )
A = log ( 7/3 )
Hence , the logarithmic equation is solved

We are given:
The function: y = -16t² + 64
where y is the height from ground, t seconds after falling
Part A:
when the droplet would hit the ground, it's height from the ground will be 0
replacing that in the given function:
0 = -16t² + 64
16t² = 64 [adding 16t² on both sides]
t² = 4 [dividing both sides by 16]
t = 2 seconds [taking square root of both sides]
Part B:
for second droplet,
height from ground = 16 feet
time taken = t seconds
acceleration due to gravity = 10 m/s²
initial velocity = 0 m/s
h = ut + (1/2)at² [second equation of motion]
16 = (0)(t) + (1/2)(10)(t²)
16 = 5t²
t² = 16/5
t = 1.8 seconds (approx)
Therefore, the second droplet takes the least amount time to hit the ground
Suppose the grades of a certain exam are normally distributed with a mean of 72 and a standard deviation of 8. The instructor is going to award bonus points to all students whose grade is in the top 5%. What is the minimum grade a student needs to have to qualify for the bonus points
Answers
Answer:
The minimum grade a student needs to have to qualify for the bonus points is of 85.16.
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 72 and a standard deviation of 8.
This means that [tex]\mu = 72, \sigma = 8[/tex]
What is the minimum grade a student needs to have to qualify for the bonus points?
The 100 - 5 = 95th percentile, which is X when Z has a p-value of 0.95, so X when Z = 1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 72}{8}[/tex]
[tex]X - 72 = 1.645*8[/tex]
[tex]X = 85.16[/tex]
The minimum grade a student needs to have to qualify for the bonus points is of 85.16.
A rectangular prism has a base with a length of 25, a width of 9, and a height of 12. A second prism has a square base with a side of 15. If the volumes of the two prisms are equal, what is the height of the second prism?
Answers
Answer:
Step-by-step explanation:
the volume of a rectangle is length x width x height, so the volume of the first rectangle is 2700.
the square has a length and width of 15 with a missing height. because they have the same volume, you can plug in the length and width of the square with the volume of the prism to find the height
v = length x width x height
2700 = (15)(15)h
2700/225 = h
the height is 12
The equation for calculating the volume of a rectangle is shown below:
volume= length × width × height.
Hence, the height of the second prism is [tex]12[/tex].
What is the volume of the rectangle?
The equation for calculating the volume of a rectangle is shown below:
volume= length × width × height.
A rectangular prism has a base with a length of [tex]25[/tex]
A rectangular prism has a base with a width of [tex]9[/tex]
A rectangular prism has a base with a height of [tex]12[/tex]
The volume of a first rectangular prism is
[tex]v=(25)(9)(12)\\v=2700[/tex]
A second prism has a square base with a side of [tex]15[/tex] as we know the sides of the square are equal so by substituting the values in length and width we find out the height of second rectangular prism
[tex]v=(15)(15)h\\2700=225(h)\\h=\frac{2700}{225}\\h=12[/tex]
Hence, the height of the second prism is [tex]12[/tex].

the required equation for the cost of any weight of gold is:
C.
600W=C is a required equation.
Answer:
600W = C
Step-by-step explanation:
First we must identify the relationship between weight of gold and cost of gold.
We can do this by dividing cost by corresponding weight.
7200 / 12 = 600
13200 / 22 = 600
19200 / 32 = 600
each proportion has an outcome of 600
Therefore Cost = Weight times 600 or C = 600W
